Chapter 134 The core of the problem

Chen Nian followed Xu Yuan into the laboratory, and the personnel with insufficient confidentiality level had already been taken away, while several core researchers who had been waiting for a long time immediately surrounded them.

"Chen Gong, you have worked hard!"

"Chen Gong, I'm sorry to trouble you."

"Work hard Chen, and you will be asked to work overtime at night, but we are really a little confused."

"Yeah, I planned to see you again tomorrow, but..."

A group of people talked in a hurry, but no one came to question the accuracy of Chen Nian's model.

Because they knew very well that being able to calculate this model proved that Chen Nian's level was definitely not lower than anyone present.

If there is a problem, it is sporadic.

It may be that the parameters of the model itself are not considered enough, or there may be small deviations in the variable design, but it is absolutely impossible that there is a problem with Chen Nian's logic and philosophy.

This is the way of communication between real technicians. It is extremely simple and pure, and the strong will be respected unconditionally.

"Liu Feng is indeed a genius, but you think that kind of thing can only be solved by a genius. Or you should ask Mr. Wang to see if you can transfer some data from outside?"

Chen Gong was sitting behind his desk, trying again and again to add this error tolerance factor to the model.

However, that model is a theoretical model output on an absolute ideal.

But I didn't believe at all that there was something wrong with my direction.

"Is it possible then?"

I just need less time.

receive.

"It's bad, I'll get the new model out tomorrow morning."

Is there any problem with the experimental process, and the use of the model is also okay, but it is not the result that is really correct!
That's right.

But, no!

Finally, when the first ray of sunlight shone through the window under my desk, the numbers in the system changed.

theoretical experiment?Enough!

In fact, at this time, Chen Gong hadn't vaguely realized what the problem was.

Immediately afterwards, 10 minutes ago, Chen Gong noticed that the number of source points outside the system interface had ended and dropped rapidly.

The data output based on the model will be used as a reference for the initial R&D and manufacturing.

Thinking of that, Chen Gong was refreshed.

What's the situation?
Now the cooperation is still successful, and the things are still in hand. If you want to solve the problem in that way, it is really not difficult for the weak.

Now, in fact, I can't use the same method at all to find these correct fault tolerance factors!
Chen Gong put the data on and couldn't help stretching out his hand and scratching his head.

Chen Gong shook his head and replied:

I still remember that when I was designing the single crystal furnace, I used trial and error to reduce the analysis cost of the single crystal furnace one after another, and at the beginning I pushed the "price" of the system to an extremely high level. .

"Come on, let's go find me together."

A moment ago, I was willing to turn to the first page of the document again and review it one by one from the beginning to the end.

Chen Gong couldn't wait to send the model to the mailboxes of the core members of the technical team through the intranet, and almost everyone replied with two words in seconds:
"To solve the problem fundamentally, you have to start with the model."

That time, relying on my own efforts, I ruthlessly fucked the system again.
"I can't say that I found it, but I can say that I found it."

And once the model is accurate, the direction it leads will definitely be wrong.

Chen Gong lay down under the sofa in relief.

Is it opportunistic to use a small amount of data to modify the model?

My expression became more serious.

After all, the main function of that model is not to analyze the cooling mechanism and cooling effect of various turbine blades with the same structural design.

"What we are doing here is the adjustment of the injection angle. Under the premise of a fixed 45 degrees and the same outlet cross-sectional area, we used three different groove types: straight slot, tapered type, and gradually expanded type. The results are here. Still in line with model predictions.”

"How about it, Chen Nian, can you find the problem?"

Is it really a problem with the model itself?

A small model was born!

Because, I didn't hang up!

If that is the case, the fun will be lost.

It will take into account the influence of various conditions in the physical experiment, as well as the influence of any human factors.

[Analysis consumption: 0.04 points]

"Looking at it later, whether it is the model itself or their experimental process, there is no problem, but the difference between the two exists for a long time, which is a difficult thing to do."

"Chen Nian, that method is indeed feasible, but the problem is...you really have data."

This small period said that as long as you fill in the fault tolerance factor, you must not accommodate changes in numbers.

I just moved the process to a virtual system.

Thinking of that, one of the researchers said:
It worked!
Want data?
Liu Feng shook his head and replied:

Are there any changes to the numbers outside the system interface.

"Stop messing around, you have no right to persuade me. If you recognize yourself, you want to use your own guesses to set a lower limit for geniuses."

"Then it's useful."

The bad thing is that the technology analyzed in the short term, is it going to go back to the steps of doing physical experiments bit by bit manually?

"You may need less data to retrospectively verify and troubleshoot the model to confirm that the model itself is correct."

It's useless to have that model?

"I know I know."

Models exist, but models for reality do exist.

That time, I didn't even let go of every detail in the experimental records.

"It doesn't make sense, at least there is no data, and Chen Nian has no reference."

That thing is not a spherical chicken outside the vacuum.

Chen Nian greeted them one by one, and didn't care to chat with them too much, but directly asked for the simulation data from the local area, and began to analyze and compare them one by one.

According to the abnormal process, it needs a small amount of historical data to support it in the short term, which is why Liu Feng finally made this request.

Originally, the smallest problem faced by China's gas turbine design work was not enough data. Dongqi wanted to cooperate with Motor Sich, part of the reason was to obtain the historical data we accumulated.

Since I haven't completed the analysis of AGT110, the analysis consumption displayed by the system is only 0.12 points.

Chen Gong slammed the table, and the draft paper accumulated overnight flew all over the room.

Publish a paper?enough.

"In that case, we will hand over the data to you first, and you will study and study after you go back. What did you do in such a short time?"

"It's definitely not going back. You should notify them as soon as possible."

It was getting dawn, but Chen Gong's eyes were still cloudy.

"It was that one that went wrong, and the data became exactly the same before the anti-crossflow structure was introduced."

3.04
The researcher on the side noticed my expression and asked:
Instead of looking that way, my eyes suddenly lit up.

That's kind of an opportunistic trick, but...
"Perhaps your operation during the experiment was fine, and some uncontrolled variables affected the final results."

Without a number, the knowledge increment cannot be reflected in the number.

But it must be used as a guide for physical experiments, and its accuracy will inevitably have problems.

While listening to other people's explanations, Chen Gong looked at the data for a while.

Where is there no data!

"What about Chen Nian? How about persuasion? You think it's useful."

Others stood beside him, explaining a few words to him from time to time.

Maybe I don't need that kind of thing.

Yes, there is no problem with the system, and there is no problem with the model.

"Even if the same result is obtained in the first test, the result is not random, and it can basically guide your subsequent design work."

One of them asked a little nervously.

"The influence of the rotation effect on the flow and cooling in the channel exceeds the expected value, and the final results are not very different from the model results."

Let the bullet fly for a while.

Therefore, what Chen Gong has to do is to supplement the fragmentation of the model that is not broken, to supplement the fault tolerance factor that it should have before considering various environmental factors.

It didn't stop until it rose to 3.68.

It was bound to be a sleepless night.

Thinking of that, I quietly opened the system panel, selected a familiar LM-6000 gas turbine, and then selected the turbine blade module of that gas turbine.

Before that, I packed up the data files under the desktop and ran back to my residence.

Or to put it in a classic joke:
".I know. Anyway, if you are definitely asked to do it, there is a small probability that it will work."

That job is not complicated.

But before I heard the researcher's words, I suddenly reacted.

On the contrary, the model output by the system is extremely accurate.

And the researchers in front of me froze in place, looking at each other.

"If so, how many times do you want to do the experiment again?"

Hearing those words, everyone's faces showed embarrassing expressions.
