Chapter 247
"Besides, inviting Xiao Yi here today can be regarded as a preliminary achievement of our goal."
"He is indeed interested in nuclear fusion."
...
Time passed quietly.
After Xiao Yi returned to the Science Island Laboratory with a pile of information, he devoted all his time to the structural research of the Eastern Super Ring.
Based on the information above, he slowly outlined every detail in the Perfect Project.
It took about 4 days, and finally he finished reading all the information and completely constructed an Eastern Super Ring in his mind.
"Finally got it."
In the office, Xiao Yi closed his eyes and carefully observed the complex structure in his mind.
It should be noted that the complexity of the Tokamak device ranks among the top among all scientific instruments and is the pinnacle of modern scientific instruments.
It is obviously difficult for one person to fully understand such a structure.
But fortunately, a person who cheats has no problem at all.
Through the effects of the Perfect Project, Xiao Yi can fully grasp every detail of the Eastern Super Ring in his mind and control it.
"Well... let's not worry about the first wall material and other things for now. The most important thing is the control of plasma flow."
Xiao Yi began to control the changes in the overall structure, and the most important thing is the magnetic field.
Thinking of this, he also began to control the changes in the magnetic field in his mind.
However, limited by the limitations of the tokamak structure, no matter how he optimizes, he will face a very important problem.
"How to use fusion energy?"
Xiao Yi frowned.
As the most successful fusion device today, the tokamak device has the greatest advantage of its control over high-temperature plasma. It can accurately control high-temperature plasma in a ring cavity. No matter how high the temperature and how fast the plasma is, it must be controlled by the magnetic field.
However, its advantage is only in the constraint.
It can only be constrained, but not used, just like burning a fire for warmth, and in order to prevent the fire from going out, it is completely covered so that the temperature inside cannot be transmitted.
Obviously, this is very stupid.
In this way, even boiling water cannot be properly boiled.
Xiao Yi touched his chin and frowned to think.
There is currently something called a tritium breeding blanket, in which the lithium can react with high-energy neutrons to produce tritium, provide fuel for nuclear fusion, and absorb heat, which can then be transmitted to the outside to generate electricity by boiling water.
But there is obviously a problem. When these tritium breeding blankets react with high-energy neutrons, they will inevitably be damaged and gradually lose their effectiveness. At this time, we must consider how to take out these breeding blankets and replace them with new ones when fusion occurs. We can't stop the operation of the reactor as soon as they are damaged.
In addition, the most important energy of nuclear fusion is not only in these high-energy neutrons, but also in those plasmas.
How to use these high-temperature plasmas?
The exchange of heat still requires direct contact. It can't rely solely on the energy brought by thermal radiation to exchange, and direct contact will cause loss.
As for the magnetohydrodynamic generator, although it is also a good idea, it still faces a key problem. How to control the high-temperature plasma to pass through the magnetohydrodynamic generator?
With all kinds of problems lingering, Xiao Yi's brows are getting more and more furrowed.
As he simulated more in his mind,
Finally, he came to a conclusion.
"Tokamak... has a big problem."
Chapter 218 Materials! Materials!
Time passed slowly.
Although Xiao Yi thought that the problem with the tokamak device was big, he still tried to simulate more times in this direction.
After all, no matter what, the tokamak device is currently considered by the academic community to be the most likely device to achieve controlled nuclear fusion. It does have considerable advantages. Its structure is simple - at least it is much simpler than fusion devices such as stellarators. At the same time, it can also achieve strong confinement of plasma, etc.
If it is not necessary, he will not completely abandon the tokamak.
For this reason, he tried spherical tokamaks, double-ring tokamaks, D-shaped, elliptical and other tokamak structures in a few days.
However, no matter how he changed, the final result was almost the same.
Constraint is easy, extraction is difficult.
"Does it mean that we still need to give up the tokamak in the end?"
Xiao Yi couldn't help thinking in his mind.
Among various thoughts, he finally began to change his mind and temporarily set his sights on the stellarator.
Stellarator is the most studied nuclear fusion device besides tokamak. Its biggest disadvantage is that it requires high manufacturing precision.
The name of stellarator comes from the simulation of nuclear fusion inside stars. Its English name is Stellarator, which means star generator.
Unlike tokamak, which mainly relies on toroidal and poloidal magnetic fields, stellarator uses a series of twisted and deformed magnetic field coils to generate complex three-dimensional magnetic fields.
These twisted and deformed coils also bring considerable difficulties to the production process.
After all, from the design purpose, these coils are required to provide a sufficiently accurate and stable magnetic field to achieve control of the internal high-temperature plasma.
However, if there is a slight deviation in the manufacturing process, then under extreme conditions such as high temperatures of hundreds of millions of degrees, it is very likely to cause great damage to some parts of the interior that are not expected to be worn, thereby reducing the life of the stellarator.
Even the possibility of accidents cannot be ruled out.
So far, no relatively successful stellarator has been developed.
However, it doesn't matter to Xiao Yi, anyway, he mainly refers to the internal structure of this device.
There is no way to get the design drawings directly like the Eastern Super Ring, but it is not particularly troublesome for Xiao Yi. According to some papers and information available on the Internet, he directly launched the perfect project and built one in his mind.
In this way, several days passed.
…
Time is gradually approaching the end of the year, and of course a lot of things happened during this period.
In terms of the PDE Industrial Alliance, because Xiao Yi completed the proof of the generalized conditions of the NS equation, more companies are more optimistic about the prospects of the PDE Industrial Alliance, and therefore it has once again attracted a considerable number of companies to join, among which the proportion of foreign companies has also increased.
The PDE Industry Alliance can gradually be called an international organization.
On the other hand, the United Mathematics Conference held in San Francisco this year has also ended.
At this joint mathematics conference, quite a number of mathematicians were looking forward to seeing Xiao Yi's NS equation proof report at this conference, but unfortunately, they did not receive any relevant information until the day before the meeting.
Just as they were disappointed, they learned from the China University of Science and Technology that Xiao Yi would hold a NS equation proof report in mid-March.
As soon as this news came out, it immediately attracted widespread attention in the academic community.
Although the description in the paper is detailed enough, people still look forward to Xiao Yi's report to provide more explanations for the academic community.
For a time, quite a number of mathematicians and mathematics enthusiasts from various countries who wanted to attend this report bought tickets to China.
It just so happens that there is a 144-hour visa-free policy in China, which means there are six days, enough for them to attend a report and even travel here for a few days.
After learning about this, the governments of Hui Province and Feicheng were even more delighted.
Just kidding, how could they be able to hold such an international academic conference, and even attract the world's top mathematicians.
In the past, such activities were held in Shangjing, such as the International Congress of Mathematicians in 2002, and Xiao Yi's previous report on the proof of the Goldbach conjecture.
They could only envy such important academic conferences.
Unexpectedly, now they finally have such an opportunity.
It seems that the money spent on Xiao Yi at the beginning is still increasing!
So in order to welcome this important report, the provincial and municipal governments began to make relevant preparations.
Including the preparation of the venue, and how to welcome those international mathematicians at that time.
Of course, it is not just mathematicians, but also mathematical physicists, fluid mechanics experts and other related researchers, who will not miss this report. Although they may not understand the mathematical proof, this does not prevent them from learning about Xiao Yi's space from Xiao Yi.
As we all know, Xiao's space is the key to prove the NS equation. Similarly, using Xiao's space to simulate fluid is also a recognized good method.
In short, the foreign tourists expected to come to China this time cover a relatively wide range, and they are generally highly educated. For China, such talents are also needed.
What if a few talents can be retained?
It is hard for the staff responsible for preparing for this report meeting.
The Chinese New Year is coming soon, and they still have to prepare for the report meeting that will start in March.
However, considering that this report meeting is derived from the proof of a world-class mathematical problem and is related to Xiao Yi, they are not so uncomfortable in their hearts.
After all, it is a report meeting that makes them Chinese people proud.
…
February 5, 2024.
Institute of Plasma.
There are only four days left until the New Year's Eve on February 9.
And the Eastern Super Ring has also made all the preparations for the ignition.
