Scholar’s Advanced Technological System

At the same time that Connie took the cooperative R&D agreement, Professor Pablo Herrero sent a doctoral student to Lu Zhou.

However, it is not here to Princeton.

Instead, head to the Sarrot Institute in California.

With the signing of a cooperative R&D agreement, research on superconducting materials has begun. The two research teams have joined forces and the progress of the project is like a wing.

However, even if the situation is good, Lu Zhou does not expect to get results immediately.

The essence of science is trial and error, and there are still many "errors" that they need to try.

Superconducting materials are only one part of nuclear fusion engineering, but not all of them.

With the launch of the superconducting topic of carbon nanomaterials, Lu Zhou also began his theoretical research on plasma.

Regarding the controllable nuclear fusion of magnetic confinement, both tokamak and imitation star are faced with common problems. The three core elements are the high temperature, high density, and long-term constraints!

The former solution is still a lot of things. The more common ones are laser ignition, the heating of the plasma itself, and the compression of the plasma volume. Of course, a variety of schemes can also be used together.

However, the real difficulty is the high density and long-term constraints of the latter two.

Plasma is not a very good thing. According to the Reynolds number formula re=pvd/, the high-density plasma bound by the electromagnetic field has a large Reynolds number, and any tiny disturbance will make the whole plasma. The system produces turbulent, irregular turbulence.

Relatively speaking, the imitation star has certain advantages in the constrained plasma, and it requires less consideration of many disturbance factors than the Tokamak.

However, even if there are a lot of disturbances, it is still not an easy task to constrain these restless plasmas in a small space.

The power of theory is great here.

When there is a theoretical model that can be relied upon and concise, even if it is just a phenomenological model that is easy to use, it can have an extraordinary meaning for the entire nuclear fusion project.

It can be said that as far as the current research is concerned, one of the bottlenecks faced by the controlled nuclear fusion technology in the theoretical field is that it is difficult to establish a reliable theoretical model for the plasma in a specific fusion device.

This is exactly what is bothering Lu Zhou.

Whether it is the Euler-Lagrange equation or the ns equation, these seem to express very concise theories, and when used to solve specific problems, the difficulty increases exponentially.

If the existence and smoothness of the ns equation is a mathematical problem of the century, then the turbulent phenomenon of the viscous fluid that satisfies the ns equation is a century of physics.

The "turbulence phenomenon of plasma" he studied is part of the puzzle of this century.

In the office of the Institute of Advanced Studies, Lu Zhou, sitting at the desk, stared at the FRP cup on the table, as if he was in a daze.

The cup is not big, and it is similar to the lid of the thermos. The liquid in it is like a boiling water, and it constantly overflows the white smoke from the edge of the cup.

With the teaching plan coming over, Vera, who is preparing to report on the teaching of the number of lectures in the previous section, curiously looked at Lu Zhou, who was in a daze.

In her impression, Lu Zhou rarely spends his time in a daze.

"Professor, what are you doing?"

“Looking for inspiration.”

Obviously, Lu Zhou is not in a daze, but the idea is in a deadlock.

Staring at the liquid in the cup, the nib in his hand began to lightly click on the notebook.

Although there is only a short line of equations on it.

[p{?v/?t+(v.Δ)·v}=-Δp+pg+Δ2v]

The equation itself is not difficult, the left is the momentum change rate of the fluid unit, and the right is the various forces acting on the fluid unit.

However, there is no difficulty, just the equation itself...

Vera didn't bother him to find inspiration, just curiously accompanied him and stared at the cup on the table.

Gradually, the white smoke that overflowed from the cup was getting weaker and weaker, and the liquid in the cup was getting less and less.

After a while, the liquid in the cup disappeared completely, and Vera blinked and looked closer.

"It has disappeared."

"Yes."

Lu Zhou did not explain anything, indicating that Vera stepped back a few steps.

Then he put on the insulated gloves that he threw at the corner of the table, and lifted a short, fine liquid bottle from under the table, like alcohol, and poured it into the glassglass cup.

The FRP cup was refilled with a transparent liquid, the liquid surface re-boiled, and white smoke was emitted.

After the liquid helium bottle was put down, the boat stayed at a safe distance and continued to watch the boiling liquid in the cup quietly.

The liquid helium at ultra-low temperature exhibits a superfluid phenomenon, the viscosity coefficient is close to zero, and the Reynolds number tends to infinity, which is regarded as a fluid close to the ideal state.

Although it seems that it is more uncomfortable than a "stationary" liquid, from a mathematical point of view, the amount of computation involved is much smaller.

In a sense, the plasma in a magnetically constrained vacuum chamber is also a presence with a large Reynolds number. It has a large density p, and a small diameter d, but because of the viscosity coefficient, it is not as exaggerated as liquid helium.

And this also means that its mathematical form is far more complicated than the liquid state of the superfluid state...

"Professor, why do I feel that the office is so cold?"

Sitting on the other side of the desk, Hardy hugged his arm and shuddered, and looked at Lu Zhou.

"Because I fell a little liquid." An understatement of something that was unspeakable, Lu Zhou suddenly thought of something, looked at Qin Yue sitting on the edge of the window and said, "Qin Yue, open the window for me. ”

"Good professor." Qin Yue put down the pen in his hand and went to open the window.

After the window opened, the office was getting warmer.

Suddenly aware of what, Hardy began to quietly clean up the things on the table, ready to go.

After taking note of his actions, Lu Zhou asked: "Where are you going?"

With a backpacker's hand, Hardy smiled slyly. "I... I suddenly remembered that there were still a few documents that I didn't read. I had to go to the library."

"Hey, there is no poison, don't be so nervous," Lu Zhou sighed. With the gloved hand, he took the FRP cup to the side of the window and let it sunbathe.

In contrast, this stuff is more dangerous.

If the finger accidentally touches it, it is light to freeze a layer of skin.

Going back to the desk and sitting down, Lu Zhou suddenly thought of something, and looked at Vera.

"Have you studied the partial differential equation?"

After thinking for a moment, Vera nodded, but shook her head again. "I have studied... but there is not much research. Is there anything I need to help?"

Lu Zhou thought for a while and shook his head. "No, still forget, you continue the subject of hail guessing."

Now there are three people in the research group of Hail's conjecture. If Willa is taken away from the research group, only relying on Qin Yue and Hardy, he is afraid that he will never see the day when the subject is completed.

The little girl’s expression was slightly lost.

She really wants to help the professor.

But sure enough, her ability is not enough...

Suddenly I thought that there was still someone in my office. Lu Zhou looked at Wei Wen, who was sitting in the corner of the office and looking at him from time to time.

"Wei Wen, do you have research on partial differential equations?"

It seems that I finally waited until the professor looked at this side. Wei Wen’s face pushed the glasses with a blank expression, but the corner of his mouth was a smile.

"Yes, what happened?"

Partial differential equations are one of the areas he is best at in addition to functional analysis.

At the undergraduate level, he followed Yan Da’s professor and participated in similar research.

It’s been a long time since Princeton came, and now he is finally waiting for this opportunity to make a big difference.

For this day, he has been preparing for too long.

He will use his strength to prove that he is the second strongest presence in this office!

Lu Zhou thought about it and said: "I am going to open another topic about the ns equation."

The arc of the corner of the mouth is getting stiffer, especially after hearing the name of the ns equation, the smile on Wei Wen's face looks... seems to be less confident.

However, Lu Zhou did not notice his expression.

What he needs most now is the manpower. Even if he can help a little, it is good.

Of course, it is not enough to be Wei Wen alone. Even if his ability is outstanding enough, it is only relative to other graduate students.

The index finger was gently lit on the table, thinking about who else could help the boat, his eyes suddenly lit up and slammed up from the office chair.

"Yeah, how did you forget that person..."

Whispered to himself, Lu Zhou’s voice was a little excited.

If it is him, I can't help but really help myself!
