Chapter 292 I am willing to go to the scene
"Let's start with the steam generator."
A steam generator is a mechanical device that uses the thermal energy of fuel or other energy sources to heat water into hot water or steam.
To put it bluntly, whether it is conventional power or nuclear power, it is essentially the process of boiling water.
It's just that the way of boiling water is different.
Xu You first designed a sketch of the steam generator on the computer according to the requirements of Code Five.
According to demand, this steam generator is the heat exchange between the first and second circuits.
While designing, Xu You was also deriving relevant formulas.
"The working fluid on the primary circuit side is coolant. The coolant pipeline is divided into multiple nodes along the flow direction, among which the mass conservation equation and energy conservation equation need to be satisfied..."
After focusing on the design of the model and the derivation of the formula.
The whole process is an extremely complicated physics problem.
However, this is completely different from the questions Xu You did when he was in school .
Those questions are relatively simple, and many conditions are directly ignored. You only need to analyze based on the ideal model.
In actual design, all issues must be taken into consideration and those conditions cannot be idealized directly.
Another difficulty is that there are not many reference plans for the design of nuclear power plants for nuclear aircraft carriers in China.
Most of these internal data are nuclear power plants of nuclear submarines and some fragmentary data about the United States' nuclear aircraft carriers.
These fragmented data cannot be guaranteed to be completely correct due to the way they are obtained.
Xu You must clearly distinguish whether the information is correct or not to help him design the nuclear power plant of the aircraft carrier.
And just like that, another ten days passed.
Xu You completed the design of dozens of model diagrams and the derivation of relevant theoretical formulas, and wrote several notebooks.
The preliminary design of the mathematical model of the entire nuclear power equipment has finally been completed.
During these ten days, Xu Youming apparently spent more than a hundred hours, but in fact he had spent several hundred hours in deep learning.
Among them, there are many more efficient flow states.
It can be said that the design of each small model and the derivation of each formula contain Xu You’s full of hard work.
With their own mathematical models, Xu You, Fan Haisheng and others started another round of meetings.
"Professor Xu , have you really built a mathematical model of a nuclear power plant so quickly?"
They were all amazed at Xu You's speed.
Even for a team, it is difficult to complete the design of a model of this level in such a short time.
It seems that what they said, that Xu You alone can defeat an elite team, is not just talk.
"Well, the initial version of the mathematical model has been completed."
Although Xu You is very confident in his mathematical model.
But before the model is verified, Xu You still has to leave himself some wiggle room.
Next, Xu You explained some key contents of the model.
I don’t know how many days it will take to explain the model from beginning to end.
Xu You spent several .
"The K value here can be obtained based on the heat transfer principle of the cylinder. The Rw is obtained from the formula of the thermal resistance of the tube wall. The heat transfer between the working fluid on the primary side and the working fluid in the secondary side subcooling section is single convection heat transfer, and the heat transfer coefficient is calculated according to the Dittus-Boelte formula. The heat transfer between the working fluid in the secondary side boiling section is flow boiling heat transfer, and the heat transfer coefficient can be calculated using the Rohsenow formula..."
As the chief designer of Codename Five, Fan Haisheng tried his best to barely keep up with Xu You's ideas.
As for the other designers and engineers, they were responsible for different tasks, so they could not fully understand many of Xu You's explanations and could only listen with gritted teeth.
Regardless of whether everyone understood it or not, everyone could see that Xu You's nuclear power plant model was indeed very complex.
However, as to whether this nuclear power plant model can really be used on aircraft carriers, no one can make a definitive conclusion at this time.
"If we can get the actual data of the United States' nuclear aircraft carrier, it can help us verify the nuclear power plant model. Unfortunately, we don't have their complete actual data of nuclear aircraft carriers."
Data of this level will be strictly kept confidential by all countries.
At this time, Fan Haisheng said:
"My idea is to use the land-based model reactor for verification. If there is no problem with the land-based model reactor, we will build a technology verification ship. If everything goes well, we will eventually apply it to nuclear submarines."
A nuclear reaction power device that is in the theoretical stage will definitely not be directly applied to a nuclear aircraft carrier, but will require multiple verification processes.
Among them, the first verification is often in the form of an onshore model reactor.
As a test facility for the development of reactor technology, the land-based model reactor can be used to test the overall technology and special technology of the reactor, and to conduct experimental verification of new reactors and their systems, equipment and components.
This is also an experimental method used by the United States in the process of researching nuclear aircraft carriers.
The location for building onshore model reactors is often in remote inland areas.
After all, even a model reactor is a real nuclear reactor.
Once an accident occurs in a nuclear reactor, the consequences will be very serious.
Building land-based model reactors in areas with fewer people can avoid risks to the greatest extent and reduce possible radiation contamination.
At the same time, the location and transportation of the onshore reactor should not be too backward.
Otherwise, transportation is also a problem.
At this time, Xu You said:
"I agree with Mr. Fan's idea. I am also willing to go to the location of the land-based model reactor and participate in the land-based model reactor experiment."
Hearing Xu You's words, everyone in the conference room had a surprised expression.
Xu You, is he actually going to take the initiative to participate in the land-based model reactor experiment?
This is an extremely dangerous experiment!
Xu You’s current value is that of a national treasure of the entire country, and he cannot afford to make any mistakes.
"Professor Xu, I can't let you go to the scene. If you make the slightest mistake, we can't take the responsibility."
Now Xu You is still a professor at Ji University.
Participating in this project is not Xu You's obligation, but Xu You's voluntary participation.
If this Nobel Prize winner in physics, who was only in his early twenties, were harmed because of a dangerous experiment, the damage would be incalculable.
"Mr. Fan, I have full confidence in safety control. If I don't dare to go to the scene myself, how can I let other operators go to the scene?"
