A genius? I just love studying.

Chapter 295 The First Experiment

In a courtyard house in Beijing, in a conference room...
"Mr. Qian, news came from Amelica that they are willing to hand over the key decision-makers of S.H.I.E.L.D. to take responsibility for the Princeton incident."

The seventh-generation fighter jet has been around for quite some time, but China has remained silent. On the contrary, Western countries have started to get restless. And now, America has come forward to admit its mistake.

Nick never imagined that he would become a scapegoat after only a little over a year in office, and that his fate would be even worse than that of his predecessor.

Professor Qian nodded. "Let's ask Professor Chen for his opinion."

If possible, they do not want to start a war lightly, even though they now have an absolute military advantage. A peaceful and stable environment is more conducive to development. If it is just a matter of development speed, no one on Earth can compare with China.

If things continue to develop in this way, in a few decades, unifying the entire planet will not require the use of force.

Especially with a brilliant mathematician like Chen Hui, this process will likely be accelerated even further.

"Speaking of which, Chen Hui is really our lucky charm. The journal he founded has been gaining a good international reputation recently, and everyone's enthusiasm for learning Chinese is at an all-time high."

Mr. Qian said with a ruddy complexion.

After Chen Hui's journal was published, not only mathematicians, but also many interested netizens joined the ranks of those learning Hua Xiayu.

This will undoubtedly be of great benefit to enhancing China's international influence.

Suddenly, Qian Lao thought of something and said to Lao Li beside him, "Didn't Professor Chen apply for a supercomputer a while ago? Let's allocate Fuxi to him."

"It also lets him know that we haven't done nothing."

"Speaking of which, Fuxi was also developed with the help of his teacher, Yuan Xinyi, right? Their lineage really produces a lot of talented people!"

Old Zhao, who was standing to the side, also sighed.

"Pillars of the nation!"

Mr. Qian gave a definitive assessment.

……

Plasma Institute

Chen Hui ignored the outside noise and focused on processing the research institute's previous data for the past ten days.

Having prior experience in building weather forecasting models, Chen Hui felt much more at ease when conducting research on plasma turbulence and instability, but it was still not a simple task.

Furthermore, the two models have very different research focuses and methods.

Although both are based on the Navier-Stokes equations, the equations are extended and simplified in vastly different ways to describe their respective unique physical phenomena.

Plasma is an ionized gas composed of positively charged atomic nuclei and negatively charged electrons. The behavior of plasma is largely dominated by electric and magnetic fields, and is accompanied by extremely high temperatures, extremely high energy densities, and extremely strong magnetic fields.

The atmosphere is a neutral gas, mainly consisting of nitrogen and oxygen. Although it contains water vapor and particulate matter, it is electrically neutral as a whole. The movement and structure of the atmosphere are mainly determined by gravity, pressure gradient force, and Coriolis force.

The atmosphere has a normal temperature range of ~200-330K, a normal density, and is driven by solar radiation.

They all start from the compressible Navier-Stokes equations, but have taken different paths.

Meteorological models only involve Navier-Stokes equations, but plasma requires magnetohydrodynamic equations, which can be seen as a coupling of the Navier-Stokes equations and Maxwell's equations.

But none of this could stop Chen Hui. He now had a general idea, and he felt that his mind was clearer than ever before. He felt that he could find the answer to any problem as long as he was willing to study it.

Formulas and data kept flashing through his mind. Even with his current memory, it was impossible for him to remember several terabytes of data. However, as long as he categorized these data and found the patterns, Chen Hui could transform them into charts and graphs in his mind.

The pen moved across the draft paper, diagrams flashing through my mind, transforming into lines of formulas and symbols on the paper...

He didn't know how much time had passed when Chen Hui let out a long breath, raised his head, and looked at the gradually brightening sky. He had actually been doing this calculation all night.

Unfortunately, it was still missing something in the end.

Chen Hui understood that to truly complete the model construction, he needed to collect real data in experiments and personally witness how the plasma flowed and operated. No matter how good a model was, it ultimately had to be tested on an experimental device to determine its quality.

Furthermore, the motion of plasma is too complex to be simulated by his own brain alone. Fortunately, his application for a supercomputer has been approved. Fuxi-1 is said to be the latest quantum supercomputer developed in China, with a performance 100 times that of TaihuLight. Chen Hui is quite looking forward to it.

Stretching, Chen Hui didn't continue his arduous training and left his office for the EAST control room. Of course, before that, he decided to have breakfast at the cafeteria.

"Hey, you finally decided to come out!"

As soon as Chen Hui entered the cafeteria, he met Academician E Weinan.

It was lunchtime, and the cafeteria was packed with people. Everyone was looking at Chen Hui, curious about this person in charge who hadn't shown up for over ten days.

Good morning, Mr. E!

Chen Hui greeted him with a smile.

He should remember the kindness shown to him that led the other party to give up their current job to come over because of his words.

Good morning, junior brother!

Yang Chi and Deng Ting, who were standing behind E Lao, also greeted Chen Hui, still habitually calling him their junior brother.

They had already graduated, and because they did well under Mr. E, they joined Mr. E's team after graduation and are now key members.

Chen Hui gave Yang Chi and his companion a bright smile, which felt particularly warm. "Good morning, senior brothers and sisters."

"Junior brother, how are you doing? Have you made any progress on your research?"

Yang Chi asked curiously.

They were already used to Chen Hui's secluded research methods; usually, Chen Hui would not emerge from seclusion without producing results.

"It's still a bit short," Chen Hui answered truthfully.

"Then you'll have to slow down a bit; our research hasn't made any progress yet."

E Weinan laughed heartily as he spoke.

Their main purpose in coming here this time is to study higher-performance first wall materials and divertor materials. Although they had some experience in high-temperature resistant materials before, first wall materials, in addition to high-temperature resistance, also need to be radiation resistant, which is still a completely new problem for them.

"Not so fast."

Chen Hui shook his head with a wry smile. He was indeed confident in solving the problem, but not now.

Some people took their breakfast, sat down at the table, and started chatting.

"Do you think Professor Chen can really solve that problem?"

On the other side of the cafeteria, researchers from the Plasma Institute were discussing in hushed tones.

"Probably, after all, he proved the Navier-Stokes equations. If there's anyone in the world who can solve that problem, it can only be Professor Chen!" "But he's been here for half a month and hasn't even been to the lab. Applied research is different from theoretical research."

"They probably haven't adapted to life here yet."

"Why worry about so much? Let's just do our own thing."

"Controlled nuclear fusion! I wonder when it will actually be completed."

Chen Hui was unaware of the discussions surrounding him. After breakfast, he met Song Yuntao in the lab. "We need to conduct an experiment!"

"No problem, I'll arrange it as soon as possible."

Song Yuntao agreed without hesitation. Chen Hui was now in charge, and Qian Lao had also instructed that all subsequent research should be based on Chen Hui's instructions. Therefore, even though conducting an experiment would be very costly, he did not hesitate at all.

"So what is the focus of this experiment?" Song Yuntao looked at Chen Hui, who had a clear understanding of his own role.

"Verify the plasma operation model."

"What? You've already finished building the model?"

"It's just a preliminary model."

"!!!"

Song Yuntao stared wide-eyed at Chen Hui.

How long has it been since?

Half a month?
Is this kid some kind of time traveler who came back from the future?

Or is this a spy from an advanced civilization lurking among humanity?

What Chen Hui said did indeed challenge his values, causing Song Yuntao to have many thoughts.

"The Fuxi supercomputer is also in place. When it arrives, the sensors and control systems will be connected to Fuxi. Fuxi will calculate the plasma trajectory in real time and then control the magnet system to complete turbulence suppression and instability elimination."

Chen Hui didn't expect to succeed on the first try, but you have to test a mule to see if it's a horse.

Five days later, in the EAST control room,
In the control room, only the low hum of the instruments and Song Yuntao's slightly rapid breathing could be heard. He looked at the incandescent white sphere of light confined by the superconducting magnetic field on the monitoring screen. The plasma inside the EAST device, with a temperature of hundreds of millions of degrees, was like a miniature sun wrapped in an invisible force field, beautiful and violent.

"Parameters are stable, H mode successfully excited!" Song Yuntao was experienced. He stared intently at the monitoring screen, where there were two curves. One was calculated in real time by Chen Hui's prediction model, and the other was the real-time trajectory of the plasma monitored by the sensor.

Soon, as Fuxi began to operate, a green curve appeared on the screen. At the same time, the sensors inside EAST also collected data and drew a red curve on the screen.

To Song Yuntao's astonishment, after the two curves initially forked, the green curve quickly adjusted and gradually began to fit the red curve.

Soon, the two curves moved in almost the same direction, with a fit of at least 99%.

Not only Song Yuntao, but everyone else in the lab stared wide-eyed, unable to believe what they were seeing.

The man in front of me solved a problem that had plagued controlled nuclear fusion research for decades in just half a month?

Chen Hui was also somewhat surprised; it was originally just a preliminary model, but he didn't expect it to perform so well in practice.

"Initiate the injection of disturbances and record the turbulence spectrum and energy transport data."

After running for a few minutes, Chen Hui told Song Yuntao that he wanted to test the model's ability to modify it in real time, so that the magnet system could be adjusted in advance before turbulence formed, thus preventing the generation of turbulence.

For the first few dozen seconds, everything seemed to be developing according to his model's predictions. The plasma rotated gracefully, and the data curve ran smoothly within the predicted channel. Chen Hui even found a seat next to him, leaned back slightly, and felt that victory was in sight.

Everything went more smoothly than he had expected.

However, in the instant he relaxed, the curve representing the stability of the plasma boundary on the monitoring screen suddenly jumped!
"Warning! High-frequency banded flow detected!" The researcher's voice suddenly became tense.

Chen Hui sat up abruptly.

On the screen, the curves predicted by the model and the curves of the actual collected data began to show subtle differences, like two threads that should have overlapped suddenly starting to dance separately.

"Impossible..." he muttered, his fingers flying across the core parameter area of ​​the model, suspecting that there was an error in some input.

According to his prediction, the model will optimize itself after the perturbation is injected, and then gradually fit the monitoring curve.

But it was too late.

That subtle disagreement quickly escalated, instantly evolving into a chasm.

It was as if another will had been born within the plasma, no longer following any elegant mathematical rules, but instead exhibiting pure nonlinear rage.

Countless small-scale turbulent vortices are generated and coupled in an instant, converging into a destructive torrent.

Immediately afterwards, the main alarm sounded shrilly, and red light enveloped the control room.

"Out of control! The plasma is completely out of control!"

The ball of light on the screen trembled violently, as if its heart had stopped. Then the light surged, the data collapsed like an avalanche, and the plasma at hundreds of millions of degrees went completely out of control within milliseconds. The enormous energy released slammed into the first wall of the device.

Despite the multiple layers of protection, this rupture was undoubtedly a shock to the device.

The control room was deathly silent, with only the mournful wail of the alarm.

Perhaps because things went too smoothly at the beginning, this sudden failure caught everyone off guard, causing a huge sense of disappointment that was difficult for everyone to accept emotionally.

"Stop the experiment!"

Song Yuntao's roar echoed in the control room, and the other researchers quickly came to their senses and shut down the experimental equipment to prevent further damage.

Everyone was heavy-hearted. The plasma out-of-control situation was too severe, causing almost devastating damage to the first wall. The losses were considerable.

In the past, they would stop the experiment before the plasma went out of control, so it wouldn't cause too much damage to the first wall. But this time, the incident happened too suddenly and too fast, and they had no time to react.

Chen Hui looked at the mess inside the EAST device and fell into deep thought.

He never expected to succeed on his first try. His model was mathematically consistent, but it lacked or was insufficient in terms of effective prediction and suppression mechanisms for such extreme nonlinear runaway states.

Although the model initially showed near-perfect predictive ability, the behavior of the plasma under extreme conditions exhibited unpredictable "nonlinear rage".

Once a tiny perturbation exceeds the critical point, turbulence will generate a chain reaction, with countless small-scale turbulent vortices being generated and coupled instantaneously. This violent and highly nonlinear evolution process exceeds the current real-time calculation and adjustment capabilities of the model.

"No matter how good a model is, it ultimately needs to be tested on an experimental device to determine its quality!"

Chen Hui sighed softly, but this failure had led him to the hidden high-frequency band flow. By making relevant modifications to the model, this problem could be effectively avoided.

Chen Hui was full of confidence!
