Chapter 297 Modeling Plasma Turbulence(2/2)
However, here, a new problem arises.
This chapter is not over, please click on the next page to continue reading! When using the Boltzmann equation to describe the turbulent flow field, a ravine blocks between the mean field and the non-pulsating field.
He couldn't find a suitable room to connect the two.
After staring at the ceiling for a while, Xu Chuan sat up straight again and picked up the ballpoint pen on the table.
No matter what, he will not give up.
Even if this is a road that no one has touched, and no one can provide him with experience and knowledge. He will conquer all the thorns and difficulties along the way, but he will not give up.
Moreover, it is precisely because of difficulties that people can have the desire to conquer, and the contentment that comes after solving the problem.
If there is no bridge between the mean field and the non-pulsating field, then he built a bridge across the abyss.
His purpose in focusing on mathematics in this life is not to take a step forward on his original peak. Now the road is at his feet, he just needs to keep moving forward.
In front of the desk, Xu Chuan held the pen and stared at the calculations on the manuscript paper and began to think.
"Theoretically speaking, plasma contains a variety of particles, at least ions and electrons, so it can be regarded as the Boltzmann equation under a multi-particle system.
"In controlled nuclear fusion, the plasma in the reactor is usually composed of 5% hydrogen ions and 95% deuterium ions."
"If the distribution function of deuterium ion particles is assumed to be fa(r,u,t)drdu, then the kinetic equation evolving in phase space is: fa/t V·fa/r Fa/ma·fa/v=(
fa/t)."
"If the distribution function of hydrogen ion ions is assumed to be."
Little by little, Xu Chuan sorted out what he needed from the source, and occasionally turned on the computer to search for some needed information.
This is a very arduous task, and there are not many papers and materials to draw from.
After all, no one has ever gone so far in the theory of plasma turbulence models.
The days passed like this day by day for who knows how long. Xu Chuan stayed in his study and didn’t go out for who knows how long. In order to build this microscopic bridge between the mean field and the non-pulsating field, he almost did nothing but eat and sleep.
Time is spent exploring possible solutions.
So much so that when Zheng Hai knocked on his door, he was startled.
"Professor, how did you do this?"
When Xu Chuan opened the door, Zheng Hai was shocked. Who was this man with messy hair, a beard that looked half-month old, bloodshot eyes, and even dark circles?
If he hadn't confirmed that this was Xu Chuan's study, he would have thought that Xu Chuan had been replaced by someone.
"What's the matter?" Xu Chuan raised his head and asked. Although the fatigue on his face was obvious, his eyes were extremely bright.
These days of busyness are not fruitless. Between the average field and the non-pulsating field, he has found a way to the other side.
"It's about the nuclear waste power generation project. The nuclear energy industrial park there has passed the acceptance inspection. A celebration banquet and commendation meeting have been arranged. Let me inform you." Zheng Hai said quickly.
"Let them drive. I won't go. I don't have time recently."
Xu Chuan replied without thinking that the research on plasma turbulence has now entered a critical node, and he did not want to interrupt his thoughts at this time and go to the capital to receive the award.
"Forehead"
Zheng Hai was stunned for a moment, and said with a mixture of laughter and tears: "This is not good, after all, you are the person in charge."
Although he is not a scientific researcher, he has followed Xu Chuan throughout the whole process, and he clearly knows the contribution of the person in front of him in the project.
It can even be said that this celebration banquet and commendation meeting were held specifically for him.
