Good luck! This village is full of billionaires

Rainbow University.

School of Physics.

In the academic lecture hall.

Sophomore Su Zirui stepped onto the stage.

He put the U in his hand into the USB port.

The title of the paper appears on the live multimedia screen——《Detailed calculations of turbulent structures! 》

See the title of the paper.

There was a sudden sensation in the academic lecture hall.

In real life, turbulence phenomena can be seen everywhere.

Clouds flying through the atmosphere, rapids in rivers, thick smoke billowing over thermal power plants, blood flowing in the arteries of the human body, etc., are all turbulence phenomena.

In physics terms.

Fluid media such as water, atmosphere and plasma have two motion states: laminar flow and turbulent flow.

Laminar flow means that the molecules of the medium move irregularly, but the fluid groups move regularly, and clear streamline images can be seen.

Turbulence refers to the fact that molecules and fluid groups in the medium are moving irregularly, and their traces will become a mess.

in the field of physics.

Scientists have been studying turbulence for more than 200 years.

To this day, turbulence is still an unsolved problem in classical physical fluid mechanics.

Countless young talents plunged into the deep pit of turbulence and never climbed out.

And at this moment…

Su Zirui’s paper turned out to be the calculation of turbulent structure!

Isn’t this too exaggerated?

Is it possible that Su Zirui really made a major breakthrough in the field of turbulence?

At that time, Hrith Rambo, a fluid mechanic in Eagle Country, once said: “I am already very old. When I go to heaven to see God, I will ask him two questions, one is about quantum mechanics, and the other is About turbulence. I guess there is an answer to the first question.”

It can be seen from this.

If you want to figure out the structure of turbulence and the physical mechanism of its generation, I’m afraid even God doesn’t know.

Since the birth of science, no physicist has been able to truly study turbulence.

Can Su Zirui really do it?

……

On the high platform.

While controlling the PPT, Su Zirui slowly said: “Turbulence is an irregular, chaotic yet organized fluid movement that changes with time and space. 23

Similar to rolling clouds, howling hurricanes, and rushing rivers, The running water from faucets, the vortices generated by aircraft taking off and landing, the entire atmosphere of the earth, the gas vortices on the surface of Jupiter, etc. are all turbulent flows. Turbulence

can enhance fuel mixing, improve fuel efficiency, and have important effects on atmospheric circulation, ocean climate, and weather forecasting. Etc., all have important impacts.

Therefore, the study of turbulence has very profound theoretical significance and application value.

In today’s paper, I start from the physical mechanism of turbulence, the transition from smooth to turbulent turbulence, and when and which molecules move Disturbing the entire order of motion, what determines whether a molecule suddenly becomes unstable at a certain moment, structural calculations of turbulence, and the Navier-Stokes equation that describes fluid motion, I will tell you about turbulence in detail……”

Hear this.

All the students and professors present were sitting upright.

They listened attentively to Su Zirui’s presentation of the paper.

If the structure of turbulent flow could really be calculated.

The entire physical world will undergo earth-shaking changes。

……

Su Zirui spoke eloquently on the stage: “The energy gradient theory in physics is used to study flow stability and turbulent transition.

The results found that in transitional flow, the mechanical energy gradient in the flow field along the normal direction of the streamline It plays a destabilizing effect on the flow, and the mechanical energy gradient along the streamline direction plays a stabilizing effect on the flow. The stability of the flow depends on the ratio of these two quantities. This ratio is a dimensionless variable and is defined as the energy gradient function. Its physical meaning is a local Reynolds number. Whether

turbulent transition occurs or not depends on the size of the energy gradient function in the flow field and the dimensionless amplitude of the disturbance.

Under the action of unsteady disturbance, when a certain position in the flow field always When the vector direction of the mechanical energy gradient is perpendicular to the velocity vector, the local energy gradient function value becomes infinity, and this point becomes the singular point of the Naver-Stokes equation. At this singular point position, the flow velocity suddenly changes to zero, and the velocity occurs at the tip

. The pressure generates a peak.

In fact, this is the beginning of turbulence.

Please look at the big screen.

This theoretical prediction of flow field changes is consistent with the experimental results. This is the burst site of turbulence found in the experiment.

Use the Poisson equation analysis method It is once again proved that the point where the mechanical energy gradient and the velocity vector are perpendicular to each other is a singularity in the flow field. Through

strict mathematical proof, the necessary and sufficient condition for the generation of turbulence is the singularity of the Navier-Stokes equation in the flow field.

Turbulence is caused by nonlinear instability caused by singular points caused by velocity discontinuities in the flow field. The

occurrence of turbulence depends entirely on the magnitude and direction of the mechanical energy gradient in the flow field. Reynolds number

in Newtonian flow Changes in Re and changes in the Deborah number De in non-Newtonian flow only affect the change in the mechanical energy gradient. Theoretical analysis results and a large number of experimental results

and Navier-Stokes The results of the direct numerical simulation of the equation are consistent.”

At this point.

Su Zirui continued: “My definition of turbulence is that turbulence is the most stable dynamic dynamic state of fluids dominated by mechanical energy gradients. The

maintenance of the turbulent state is the continuous nonlinearity of a large number of singular points in the flow field. This is achieved by instability.

If under the influence of certain conditions,

such as lowering the Reynolds number, the nonlinear instability caused by the singularity of the Navier-Stokes equation in the flow field gradually disappears, and the turbulent flow becomes laminar flow. state……”

……

In the academic lecture hall.

Everyone listened with rapt attention.

Su Zirui’s explanation method was simple and profound, and he explained the mystery of the generation of turbulence in detail.

His theory subverts the original turbulence theory. It is a brand-new turbulence theoretical system and an original innovative work “from 0 to 1”.。

……

Next.

Su Zirui continued to explain turbulence.

He started from how turbulence changes from smooth to turbulent, the molecular motion of turbulent flow at a certain moment, certain molecules in turbulent flow suddenly become unstable at a certain moment, the irregular trajectory of turbulent flow, the internal consequences of turbulent flow, the calculation of turbulent structure…

everything The secrets of turbulence.

At this moment, everything is displayed in detail in front of everyone.

Following Su Zirui’s narration.

The formulas displayed on the large screen span hundreds of pages, contain thousands of formulas, and involve references to nearly a hundred previous literature.

The physics teachers present listened carefully while verifying it crazily on their notebooks.

However, proving this thesis will take a lot of time.

They could only give up the argument temporarily and choose to match Su Zirui’s explanation speed.

They didn’t understand many parts of the paper.

But look at it as a whole.

The paper does not contain any logical errors。

……

Time passes slowly.

On the big screen, a lemma appeared.

Su Zirui said loudly: “From the above differential equations and various formulas, we can thoroughly calculate the internal structure of turbulent flow!”

The words fell.

There was silence at first.

Immediately afterwards, cheers like a mountain roar and a tsunami broke out.

All teachers and students in the lecture hall stood up and applauded for a long time.

The turbulence problem is solved.

Su Zirui’s battle to become a god is destined to shock the entire physics world!

……

In the academic lecture hall.

All the students from the Russell University Group have fanaticism in their eyes.

Two hundred years.

Turbulence has always been the cancer of physics.

It has cultivated many outstanding physicists, including many Nobel Prize winners.

The physics community has always believed that turbulence was not solved in the past, and now there is no hope of solving turbulence. It is estimated that turbulence will never be solved.

I never thought…

Su Zirui, a young sophomore at Xia Guocai University, would completely solve the turbulence problem!

How incredible is this?

The turbulence problem is solved, and to a lesser extent, it can better serve the industry.

For example, in the nuclear engineering industry, we can reduce the safety margin of thermal and hydraulic design, improve the economy and safety of reactor core design, and make better use of nuclear energy resources.

For example, in the field of ship design, better appearance design can be obtained, making the ship sail faster, have a longer life, etc. (To read Baoshuang novels, go to Feilu Novel Network!)

Aviation, aerospace, shipbuilding, power, water conservancy, chemical industry, ocean engineering, meteorology, marine science, astronomy and other fields will usher in a new leap and enter a new round. of the industrial revolution.

The problem of turbulence has been solved, and on a larger scale, physics can be unified.

From how dark matter and dark energy work, to the macroscopic operation process of the universe, to all the details of the quantum microscopic entanglement process, all details can be simulated without missing a beat.

Not an exaggeration.

Su Zirui can easily win the Nobel Prize in Physics just by solving the turbulence problem!

……

the other side.

School of Chemistry.

In the academic lecture hall.

Zhou Yu, a sophomore, put the USB flash drive into the USB port and read the paper.

The title of the paper is “Joule���Flash technology! Let graphene turn into a bargain in seconds! ”

When I saw this title, the scene was in an uproar.

Students and professors from Russell Group universities were all very surprised.

The current commercial value of graphene is between US$70,000 and US$200,000 per ton.

What the hell is going on that makes expensive graphene so cheap?

If graphene really becomes cheap, doesn’t it mean that a new round of materials revolution is coming?

While operating the APP, Zhou Yu introduced: “Joule thermal flash evaporation technology is a new carbide synthesis method. The

specific operation method is to use millisecond-level current pulses to pass through the precursor to bring the sample to an ultra-high temperature of more than 3000K. Then quickly cooled to room temperature.

Based on this, I successfully synthesized TiC, ZrC、HFC、VC、NBC、Thirteen important element carbides such as TaC, Cr2C3, MoC, and W2C, as well as B4C and SiC covalent carbides, show good versatility.

Then by controlling the pulse voltage, the thermodynamically stable -Mo2C, metastable -MoC11-x and -MoC11-x isophase pure molybdenum carbide is selectively synthesized.。[]

-Mo2C has the best HER performance, with an overpotential of -220mV and a Tafel slope of 68mVdec?1, with excellent durability.

Whether it is petroleum coke, coal, food waste, rubber tires or plastic waste, Joule thermal flash evaporation technology can be used to turn it into coke-free phase-controlled carbide nanocrystals in less than 100 milliseconds.

Traditional production methods such as mechanical stripping, redox, SiC epitaxial growth, and chemical vapor deposition are expensive to produce graphene.

Joule thermal flash evaporation technology can achieve low-cost, mass production of graphene with only 2.2~8.6kJg?1 of electric energy.

In my laboratory, I can produce 1 kilogram of graphene every day, and the electricity cost is only 1.06 yuan, completely realizing the price of graphene!

Joule heat flashes graphene, which can also capture greenhouse gases such as carbon dioxide and methane, making it more environmentally friendly.

Of course, since the laboratory’s daily output is very limited.

In the future, I will cooperate with the school’s scientific research units, increase investment in production, accept market application testing, and finally achieve large-scale application! ”

The words fell.

Everyone stood up and burst into applause.

Everyone knew it in their hearts.

When the cost of graphene becomes cheaper, it can improve the cost performance of batteries, aviation materials, mobile phones and other materials.

Zhou Yu’s flash graphene technology is far from large-scale There is still a long way to go before its application.

But he possesses the rarest disruptive ideas and innovations in the scientific world.

Once this technology is applied on a large scale, it will definitely set off a new round of materials revolution!

……

College of Agriculture.

In the academic lecture hall.

Xie Chenxi, a third-year female student, was chatting.

The title of her thesis is “The birth of nanopesticides, a new dimension in the agricultural field!” ”

Xie Chenxi said slowly: “Nano pesticides are an upstart in the plant protection industry and an emerging chemical technology that can change the world in the future.

Nano pesticides refer to certain pest prevention and control scenarios based on 037, through functional materials and nanotechnology. The active ingredients of pesticides exist stably in a nanoscale dispersed state in the preparation and use dispersion system, and when used, they can exert pesticide preparations with application properties that are different from those of the original dosage form. The nanopesticides I developed can perfectly solve the problem that some pesticides are difficult to dissolve

and Insoluble in water, pesticide mixing and other issues, and completely solve the environmental pollution and insect pests caused by traditional pesticides.

Nano pesticides are suitable dosage forms and supporting pesticide products for efficient operation of plant protection drones.

At the spraying site of customized nano pesticide mixing services, You can’t see the various bottles and jars of pesticides that were common before, and there is no scene of laborious mixing of various pesticides.

Just a drone pilot pours the transparent nano-pesticides customized for this field into the water. Just add and stir.

It only takes one minute to add water and medicine to 20 acres of land, completely solving the problem of pest control.

After using nanopesticides,

the average yield of crops per acre has doubled!

From a practical point of view, nanopesticides can not only Upgrading single-dose pesticides can also achieve stable compounding of multiple pesticides. The compounded pesticide preparation is transparent in appearance, thermodynamically stable, and can be stored for more than one to two years. This provides the possibility for remote customized production of pesticides.……”

Following Xie Chenxi’s narration.

The students and professors present were all fascinated.

Xia’s agricultural production and management model has basically achieved mechanization in the plowing, planting and harvesting links, but the plant protection part of pest control has become a “stuck” link.

The plant protection link has the highest technical content, the largest number of workers, the highest labor intensity, and the most difficult risk control. It is a key link to fully realize agricultural modernization.

my country’s overall climate conditions are complex, and the incidence of pests, diseases, and weeds is high and diverse. Most crops generally require multiple control during their growth cycle.

According to statistics, there are 739 species of common agricultural pests, 775 species of diseases, and 109 species of weeds in Xia, which are difficult to control and require high control technology.

Nowadays, nano-pesticides are born, which can evenly spray mist insecticides, nutrients and other drugs on crops.

It will undoubtedly bring about changes in the agricultural field!

……

at the same time.

Academic exchange seminars are being held in various colleges of Rainbow University.

Students from the Russell University Group were all crushed by the Rainbow students.

At this moment, they were all in deep shock and deep self-isolation.

Proving the Riemann Hypothesis, calculating the turbulence structure, making graphene worth the price of cabbage, and the birth of nanopesticides…

every achievement of Rainbow students makes them feel desperate!

That’s right, it’s despair!

In academic exchanges in various disciplines.

They do not have an advantage in any subject or major.

In every academic exchange, they were crushed and beaten by Rainbow students.

The Russell University Group students who come to Xiaguo for academic exchanges are all the proud students of the world’s top universities.

They came to Xia Kingdom with high spirits.

I wanted to make a name for myself in the academic field, but what I received was a slap in the face! .
