From Almighty Scholar to Chief Scientist

Seeing this result, Lin Xiao frowned.

But at this time, he realized that no matter how much he modified the model, he could not achieve true perfection, that is, as in reality, the turbulent flow continued and would never stop.

Of course, we are not so sure about this, because according to Ma Weimin’s experiment results, their longest experiment was five days, and then the turbulent flow lasted for nearly five days, and it seemed that it would never stop down the same.

Maybe, after another day, it will be able to stop?

Of course, it may take another month, and these situations are not considered.

"So, the ultimate goal is to prove the NS equation."

Lin Xiao shook his head lightly, then quickly regained his attention, and once again looked at all the new turbulence models he had built before.

Through this step-by-step construction of the turbulence model, it is also very meaningful for him to prove the NS equation.

"Well... then go ahead and try."

In the following time with the world, Lin Xiao is basically constructing the turbulence model, which is a very complicated process. As he builds the turbulence model more and more meticulously, he has no idea how to prove the solution of the NS equation. Existence and smoothness are becoming more and more thoughtful.

Until the end, Lin Xiao's analysis of this magnetic fluid propulsion turbulence model even took into account the density of the internal seawater and various other substances.

As we all know, water is non-conductive, but the water that exists in nature is basically water with impurities, especially sea water, which is full of a lot of salt.

Then, in the magnetic fluid thruster, the propulsion is realized essentially by the force generated by the conductive seawater on the superconducting magnetic field, then those seawater molecules in the seawater that can bear the force are first subjected to the force, and then gradually pushed away Go out, and those seawater molecules that have no force will stay in place and eventually become chaotic.

And considering such a level of detail, the original model is naturally more complicated.

Later, when Lin Xiao input the model into the computer and started the simulation calculation, the computer suddenly froze.

Seeing this scene, Lin Xiao was taken aback.

No way?

His computer is a computer that can be used to run deep learning, and only four graphics cards are plugged in.

It's stuck?

And just when he realized that something was wrong, smoke suddenly started to rise from the computer case next to him, accompanied by some sounds that sounded very bad.

"I rely on."

Lin Xiao couldn't help cursing, then hurried up to unplug the power, and then got the case out of the door.

There must be no problem with the data in it, otherwise he will probably be scolded.

Finally, the case was disassembled, and the place where the smoke was coming out was on one of the graphics cards. The hard disk should be fine.

However, Lin Xiao still showed a speechless expression.

What's the matter? Running the program actually broke the graphics card.

Isn't it just an ordinary turbulence model...

Uh, to be honest, the turbulence model he created really cannot be described as ordinary.

After all, his new turbulence model, compared with the previous turbulence models, has almost an exponential increase in the amount of calculations, and the load on the computer is naturally greater.

Thinking of this, Lin Xiao touched his nose, then took off the graphics card that was probably burned out, and touched it sadly: "Card, thank you for your hard work, take a good rest."

Then throw it aside.

"It's time to change."

If it is scrapped, there is no point in continuing to use it, so just replace it.

Of course, his brand new turbulence model had to be simulated, otherwise he wouldn't know what his model would look like when it actually ran, so he had to find a better computer to run it first.

So he let go of his sadness about breaking a graphics card, and began to think about what host to use next.

Ordinary personal computers basically don't need to think about it. The configuration of his computer is basically the top-level among personal computers, and the price is also very expensive.

So now you can consider overcalculation.

When it comes to supercomputing, Lin Xiao soon thought of Wang Wenguang, the director of the Xishi Supercomputing Center.

Last year, Director Wang Wenguang contacted him and said that he wanted to cooperate with Dingguang Research Institute to develop a supercomputer, and he agreed. He quickly finalized the matter and applied for funding. Lin Xiao's signature and related funding were quickly approved. It seems that they have been developing new processors for so long, and they don't know what the situation is.

After thinking about it, he took out his cell phone and called.

Coincidentally, he can also use Wang Wenguang's relationship again to use the supercomputer in advance, so as to avoid queuing up for applications at that time.

Soon, the phone was connected.

"Professor Lin, I haven't called for a long time. What's the matter?" Wang Wenguang, who was opposite, said with a smile.

Lin Xiao smiled and said, "Is my purpose so obvious?"

"Hahaha~ How about this, Professor Lin, I'll just give you an account, this account can use Shenwei anytime, anywhere, and then you don't need to call me every time." Wang Wenguang smiled, and then said.

Lin Xiao's eyes lit up, and he said, "Then thank you, Director Wang."

"It's nothing, it's a trivial matter." Wang Wenguang said.

Lin Xiao smiled, and then said: "Of course, apart from this matter, I also want to ask, how is your new supercomputing plan going?"

"Oh, this, we are still studying the new processor. We are designing 5nm for the first time, and it is the 5nm of our X5 process. The design team is still studying it now." Wang Wenguang said: "In addition, We also encountered a lot of problems, so it will take a little time."

"Is that so..." Lin Xiao thought for a while and said, "Perhaps, I can recommend someone to you."

"Oh? Recommended by Professor Lin, he must be a very powerful person."

Lin Xiao smiled and said: "Actually, I can't guarantee it, but if there are no accidents, he can at least help you. After all, you should use Anhua EDA software to design. This person He is the founder of Anhua EDA."

Wang Wenguang was taken aback for a moment, and after a while, he said in surprise, "Are you referring to that Kong Huaan?"

"Yes."

"That's it..." Wang Wenguang thought for a moment, and then said: "Then trouble Professor Lin, make sure he joins us, we need talents like him!"

Just kidding, Kong Huaan, as the designer of Anhua EDA software, naturally has the ability to design chips. big meaning.

After all, Anhua EDA is easy to use, but after all, it is a software that has only been on the market for a few months, and there is still a learning process for them. At this time, if the founder of the software they use can bring them some Suggestions, or some teaching, their research process will definitely be able to be improved again.

So Wang Wenguang immediately agreed to Lin Xiao's proposal.

"Okay, that's it, I'll call him later."

"Okay, thank you, Professor Lin."

Wang Wenguang said with a smile.

Then, after hanging up the phone, Lin Xiao soon received an account password from Wang Wenguang, which belonged to the super account of Sunway TaihuLight.

The kind of VIP, you can swim freely.

So Lin Xiao didn't talk nonsense, directly used this super account to connect to Sunway TaihuLight, and then continued to run his previous model.

With the computing power of the supercomputer, this model finally ran, but of course the speed is still not flattering.

Lin Xiao shook his head, and then let the model run by itself, while he called Kong Hua'an.

The call was connected quickly, and Lin Xiao didn't talk nonsense, and asked directly: "Old Kong, are you interested in studying chip design?"

To his surprise, Kong Huaan on the opposite side said directly: "Okay!?"

Lin Xiao was taken aback for a moment, why do you still feel a little excited even if you don't even ask this question?

Of course, he didn't ask, and said directly: "A new supercomputing processor under development, with a 5nm process, will use the X5 process."

"Okay, when?"

"Anytime, look at you."

"Then...tomorrow?"

Now Lin Xiao can be sure that Kong Huaan is very motivated about this matter.

He finally asked, "Are you interested in chip design?"

Kong Huaan said with a smile: "I became interested in EDA when I was working on it. After all, this thing is the most fundamental thing of all computers. I really want to study it now."

"okay, I get it."

Lin Xiao didn't ask any more questions, and said: "Then I will send you the phone number of the director of the Xishi Supercomputing Center later, and you can just call him. He is also very optimistic about you, so I must call you." past."

"it is good."

After hanging up the phone, Lin Xiao was still surprised by Kong Huaan's sudden change of interest, but he didn't think about it any more, and turned his gaze to the running model on the display screen in front of him again.

But at this time, he was suddenly taken aback, looking at the simulated turbulent flow above with great surprise.

"This is……?"

Chapter 351 Even more awesome!

Lin Xiao looked at the turbulent flow model on the software in front of him in surprise.

The turbulence model at this time is still in a turbulent state.

It's just that this turbulent state will occasionally turn into a regular state.

This regular state is different from the ordinary stable state before. The liquid in this regular state seems to have become a vortex state.

In the vortex state, the flow rate of the liquid is very fast. It is like pouring water from a bottle into a cup. If you turn the bottle so that the liquid inside forms a "tornado", the water will flow very fast.

Just like a fan, the gas flow generated by the fan is a kind of vortex, and in this way, the flow speed of the gas will be faster.

And the flow is fast, what does it bring?

Apparently, it has brought about greater propulsion.

For example, in a submarine, the more fluid that is pushed out at the same time, the greater its mass, which in turn brings stronger thrust.

So Lin Xiao couldn't help being excited at this time.

If the cause of this vortex can be figured out and reproduced in reality, then what will be brought by then will be an extremely powerful nuclear submarine.

Thinking of this, Lin Xiao immediately began to explore why this happened.

What magical mystery of fluid physics is hidden in the mathematical model he constructed.

……

It is not easy to find out the cause of this eddy current, but it does not bother Lin Xiao.

Anyway, he now has a super account of Sunway TaihuLight. Basically, as long as he has a model, he will go to the supercomputer to calculate it, which is very convenient.

And with his construction of the new model, the time for this vortex to appear has become longer and longer, and the number of times it has been included has also become more and more.

Ever since, in his turbulence model of the magnetic fluid propeller, there are three states in this way, one is the basic stable state, the fluid basically runs stably under the promotion of electromagnetic force, and the second is the turbulent flow state, basically It can be determined that under the promotion of electromagnetic force, a chain reaction is formed inside the liquid, and the collisions between them lead to a completely irregular flow, while the third is the vortex state, obviously in a single direction of force Under the push, such a vortex is formed, and the mystery hidden in it may not be less than a Hall effect.

In addition, according to calculations, the thrust generated by this vortex is about twice that of the basic steady state.

This means that the 60 knots calculated by Ma Weimin and the others are likely to be doubled, and the most critical acceleration can also be improved.

Once this principle can be applied to nuclear submarines at that time, I am afraid that it will not be the original dimension reduction strike, but a two-dimensional reduction strike.

Not to mention the taillights, the enemy's nuclear submarines can't even eat farts.

Of course, the premise has to be researched first.

In this way, time passed quickly.

……

The time has entered June.

"Professor, my topic is confirmed."

"Oh? It's so hard that you can still remember your topic."

Looking at Chen Mingkai who came to look for her, Lin Xiao frowned, put down the pen in her hand, stopped the research on the NS equation for now, stood up and stretched, and said at the same time, "I told you before July Hand it over, you've delayed it until July."

"Hey, didn't I always think about how to keep silent and make it a blockbuster." Chen Mingkai scratched his head and laughed.

Lin Xiao couldn't help chuckling: "It seems that you are quite confident."

"If you are not confident, do you still call you a student?" Chen Mingkai smiled, then handed a piece of paper to Lin Xiao, and said, "Professor, look, this is my topic."

Lin Xiao nodded, then took the things over, glanced at them, and couldn't help being surprised: "Richie?"

"Yes, L2 curvature bounds on ricci curvature bounded manifolds."

Chen Mingkai nodded.

He studies algebraic geometry, and this question is actually more biased towards differential geometry. This topic is very in line with his direction.
