Chapter 128: Model Error?

No matter what the UKR and the US side intend to do, for Chen Nian, his task is the same.

That is, the key technology of the AGT110 heavy-duty gas turbine will be exported as soon as possible to ensure that Dongqi can develop and manufacture this significant gas turbine as planned.

Of course, in addition to this, he will also use this gas turbine as a bait to guide Madasic to come up with as many chips as possible in exchange.

Their purpose may not be clear, but in the face of absolute interests, there is absolutely no reason for anyone to refuse.

After all, this is a super gas turbine with 110 megawatts of power.

Compared with the technology of this era, its performance can no longer be described as crushing.

Whoever gets it will have the golden key to the modern shipbuilding, heavy industry, and power industries.

Therefore, Chen Nian is very confident that the other party will definitely take the bait.

According to such a plan, Chen Nian temporarily left Dalian and went to Dongqi Group instead, just Deyang is not far from Chengdu, and if there is any problem with the J-20 project, if necessary, he can also go to the scene in time to solve it.

The importance of Dongqi Group to him is unparalleled, data, equipment, and manpower are all configured according to the highest standards, and in some respects, his authority is even greater than that of the general manager.

In such an environment, his efficiency has also been greatly improved.

In less than a week, he has completed the combing of key technologies and delivered the documents to the following researchers for preliminary verification.

If the verification is successful, the next step is to enter the structure refinement and data preparation phase.

On this day, after finishing a day's work, Chen Nian took a walk and rested in Dongqi Park to change his brain.

He drank the coconut water that the logistics department had brought him from Hainan the night before, while opening the system panel to check the recent harvest.

Since his main focus was on technical output, he did not give much weight to knowledge absorption during this time, but even so, the number of source points was growing at a steady rate.

In two weeks, a total of 1.76 source points have increased, and with the original stock, the number of his source points has reached 2.99.

And while he was looking at the panel, the number jumped up again, reaching 3.04.

It is estimated that which project has undergone technical fission and contributed to the source point for itself.

Now the growth rate of the source point is faster again, and it is estimated that it will not be long before it can break through the 5-point mark.

So what should you choose for the next technology?

In terms of the dark blue 16 project, there must be a part of the source point reserved.

After all, this time he only analyzed the technology of AGT110 itself, and those front-end infrastructure, materials, and equipment still need to be solved one by one.

It's impossible to really put all your hopes on the Madasic factory.

Even if they have the equipment and materials, they can't fully meet our needs, at most it's just a foundation.

If you want to build a tall building, you have to do it yourself.

Electrolytic machining, directional solidification, electro-hydraulic beam drilling, large fine and rare CNC machine tools

These are all issues that need to be addressed.

Thinking of this, Chen Nian secretly rejoiced:

Fortunately, the F119 was brought out in advance, at least in terms of materials, there is basically no big problem.

Especially TBC.

For heavy-duty gas turbines, this thing is too important

He gulped down the coconut juice in his hand and began to walk towards his lodgings, and the moment he entered the red zone, the researcher who had been waiting for him for a long time immediately greeted him.

"Chen Gong, you're back!"

Chen Nian looked up and saw that it was a special interface person arranged for him by Dongqi, who was responsible for all the technical and life affairs during his time at Dongqi, named Xu Yuan.

"Uh, it's back, what's wrong?"

To tell the truth, Chen Nian is actually still a little uncomfortable with this kind of meticulous care, for example, the night before, he just casually mentioned after the meeting that he would have time to go to Hainan to drink coconut water, but as soon as he woke up this morning, fresh coconuts had been placed in the kitchen, and there was a feeling of "no one knows that it is lychee".

But this time, Xu Yuan didn't seem to be polite to him.

"There's a bit of a problem with the technical team, so I'd like you to go over and take a look."

"What exactly is the problem?"

Chen Nian's expression immediately became serious, he knew that at this kind of time after dinner, if there was no real emergency, the general manager of Dongqi would not allow anyone to disturb him.

"It's about the prediction of the thermosetting characteristics of turbine blades, and the model you provided yesterday has been read by the technical team."

"However, the results of their calculations are a little different from the results you gave."

Hearing this, Chen Nian frowned.

It's not a small problem!

The so-called prediction of the flow thermosetting characteristics of turbine blades is, in simple terms, the prediction of the working load of gas turbine turbine blades.

At high temperatures, the turbine blades of gas turbines are subjected to various loads such as centrifugal force, air flow force, temperature, etc., and to ensure the safe operation of the blades, it is necessary to accurately obtain the operating conditions of the blades under the complex cooling structure.

The study of the comprehensive characteristics of flow thermosolids is the most basic means to obtain data.

If this prediction fails, the design characteristics of the turbine blades will not be accurately realized in the subsequent development and manufacturing process, which can lead to a shorter component operating life, reduced stability, and even the risk of an entire gas turbine system crash.

"What's the difference?"

Chen Nian hurriedly asked.

"The main thing is the heat exchange characteristics of the cooling structure."

"Based on the data and models you provided earlier, the technical team simulated the effect of three types of air film holes, dustpan-shaped, conical, and cylindrical, on the local cooling efficiency downstream of the orifice, but the final data results were completely different from your conclusions."

"Completely different?"

Chen Nian subconsciously repeated, extremely puzzled in his heart.

He carefully recalled the data he had previously provided, trying to find the crux of the problem.

According to the model and results provided by the system, in the range of Reynolds number 10000~25000 and blowing ratio of 0.3~2.0, the optimal blowing ratios of the three hole shapes mentioned by Xu Yuan are 0.7, 1.0 and 0.5, respectively, and when the blowing ratio is greater than 0.7, the cooling efficiency of the expanded hole is higher than that of the cylindrical hole.

In addition, the shrink-expansion hole can also expand the area covered by the air film by forming a coupling vortex, resulting in a 110% increase in cooling efficiency.

Chen Nian had also done a preliminary calculation of this data before, after all, the model was ready-made, and it didn't take much effort, but at that time, he didn't find a problem.

Could it be that the data is given to the wrong person?

Or is there something wrong with the system?

It's possible.

After all, the system gives the final data, and the model is generated from the final data.

Could it be that this set of models is only suitable for the AGT110 steam turbine?

That's not right. If that's the case, can a model still be called a model?

Chen Nian felt more and more puzzled, and he hurriedly said to Xu Yuan:

"Let's go, let's take a look, if there is really any problem, we have to solve it as soon as possible!"

"Understood, I'm waiting for you, I'll take you there now."

In terms of work, Xu Yuan did not have the style of hypocrisy and resentment, and the two of them immediately quickened their pace and walked in the direction of the laboratory.

While walking, Chen Nian secretly thought in his heart:

Hopefully there won't be a problem.

——

But even if something does go wrong, it doesn't matter.

It's not for nothing that I learned so many things by myself.

If it's really something that the system can't manage, then I'll take care of it myself!
