God of black technology

When the plane soared into the sky and sat on the plane, Wang Yun silently looked at the scene outside the window.Northwestern Polytechnical University is still some distance away from Yucheng, and Professor Li sat in front of them.The graduate students beside him asked Wang Yun questions from time to time, but Wang Yun answered them one by one.The graduate student next to him felt that he seemed to be living on a dog in the past few years.

When the plane stopped at the airport, Professor Li led Wang Yun and his graduate students off the plane.Just arrived at the terminal, the bus of Northwestern Polytechnical University, after getting on the bus, no one spoke.

Sitting in his seat, the graduate student next to him whispered, "There is something wrong with the turbulence model, the viscosity number is wrong, and..." When he said this, the graduate student glanced at Wang Yun, and said cautiously, "Anyway, when the time comes You will know when you go."

Wang Yun frowned and remained silent for a while, "Why do I feel that something is wrong with this matter?"

"In addition to our Yucheng University, there is also the National University of Science and Technology, you know." The graduate student patted Wang Yun on the shoulder and said with a smile, "The nature is different."

"???" National University of Science and Technology?Misty Grass, known as the essence of the army, is it so cute?

What kind of experiment requires the cooperation of Northwestern Polytechnical University, National University of Science and Technology, and National University of Science and Technology?Why does it feel like things are getting more and more difficult.The graduate student looked at Wang Yun's bewildered expression, and said with a smile, "Don't worry, I won't let you do anything too difficult, that is, there are some problems with CFD and turbulence models. problem. As for the CFD side, the National University of Science and Technology has a big cow to do it himself, so we don’t need it.”

"Our professor has made a lot of achievements in aerodynamics. In terms of turbulence, although no one has figured out what's going on now, you can understand it by substituting the Reynolds number."

I see.I understand the truth, but I'm just a little awkward right now.Wang Yun sat in the car silently, feeling that he was very comfortable, why did he have the feeling that he had accidentally entered a big pit.

The bus has slowly entered the campus of Northwestern Polytechnical University. The graduate student stretched his waist, looked at Wang Yun and said, "Let's go, we have not come to Northwestern Polytechnical University once or twice. We are very familiar with this place. Settle down first. , and then go to the lab to help, and I will see what position Professor Li will arrange for you later. But I guess you should be recording data or something, and the experiment will have to be restarted, so there is still a long time before you can relax, let alone The herd of animals in the mathematics center is not here now, and I am afraid that the large number of calculations will still trouble you."

There is nothing wrong with computing, Wang Yun nodded slightly, but I don't know if I can get involved with some fringe experiments just for computing.

Such a large-scale experiment is generally divided into several, or even more than ten, dozens of different experimental groups.In addition to the core part, there are various experimental groups that are more marginal.

Wang Yun reckoned that he might be able to play a role in the relatively marginal experimental group or something.After all, for the researchers of these experimental groups, the people in the number institute are relatively easy to use.

There is no separation between mathematics and science!

After getting off the bus, Professor Li arranged for a graduate student to take Wang Yun to find the dormitory. It seemed that the two of them would probably be grouped together.

While dragging his suitcase, Wang Yun looked at the graduate student in front of him and asked, "Brother, what's your name?"

The graduate student smiled, "Call me Brother He." He paused here, "I was planning to put you in the core group, but I don't know what happened, but I actually called you and me. "

"Brother He, are you also in the core group?"

"How is it possible." Brother He said dumbfoundingly, "The boss is in the core group, yes, his disciples who benefited from him are in the core group with him, but I am not in the core group, we just make models on the edge .”

"The model of the core group is different from ours. We mainly solve the problem of the viscosity of turbulent flow and the flow function of the flow field." When talking about this, Brother He paused, "The members of our experimental group are basically all from Yucheng University. Yes, but I heard that the person in charge of our experimental group seems to be a Ph.D. from the National University of Science and Technology."

"I can't say exactly what it is, we'll find out after we read it later." He Ge was talking, and took out an ID card from his trouser pocket and put it in Wang Yun's hand, "No, in the future you want to It is up to him to enter the laboratory. Although it is a marginal experimental group, it is still in this project, so it is still necessary to rely on this to enter. Be careful, if the identity card is lost, you must report to Professor Li as soon as possible. .”

"Okay." Wang Yun nodded, it seems that the subject this time is not simple.Could it be the subject of the J series fighter jets again? Thinking about it, why does it still look a little exciting?Hey, that's not right, shouldn't the J-series fighter jets be carried out in Sichuan province?Could it be—fog grass!It is one of the topics, and the cliff is one of the topics of the J series fighter.

CFD, turbulence model, these together can only make a large aircraft.

When they came to the dormitory, Wang Yun and Brother He put down the things in their hands. Professor Li walked to the door and took a look and said, "Go to the laboratory immediately, and we are already waiting for us to start work there."

"Okay." Brother He responded, and after Wang Yun changed his clothes, he walked out of the dormitory with Brother He.

Along the way, Brother He muttered, "Really, in such a hurry, I don't let people rest for a few minutes. It's a plane and a car, and I'm quite tired."

Wang Yun asked curiously, "Is such a high-intensity experiment rare?"

Brother He nodded, "It's rare, probably because I don't have access to any core research, but the boss is very busy. My brothers with Ph. Feel sorry for them..."

Wang Yun was so suppressed that he was about to laugh. When they walked to the front of the laboratory building, they put on their ID badges and saw two guards standing in front of the laboratory door.He froze for a moment, isn't this battle a bit big?

When he walked into the laboratory building, Wang Yun heard that the voice was quite noisy, and someone was talking non-stop.Experimenters wearing white coats in twos and threes hurriedly walked in the hall, chatting from time to time.

Brother He looked at the curious Wang Yun and said, "Let's go, this kind of large-scale project is like this, promise that our laboratory is here." Pushing open the door, Brother He saw a stranger wearing a white coat standing on the podium superior.He was holding a book and a pen in his hand, as if he was still calculating something.

She looks young, only 23 or [-] years old.He was rather handsome, and under the white coat, he could faintly see the olive green military uniform.

Is this someone from the National University of Science and Technology?Brother He was stunned for a moment, and wanted to go up to say hello.The man turned his head to look at them, "Aren't you from Professor Li?"

"Hmm." Brother He nodded, the man's eyes passed over Brother He, looked at Wang Yun, and then frowned and said, "Is he also a graduate student of Professor Li?"

The main reason is that Wang Yun's age is too puzzling. He doesn't look like an adult yet, and he looks pretty, so he doesn't look like an academic.And the other party is a member of the National University of Science and Technology, so he must be more vigilant about this area than ordinary universities.Therefore, the eyes that looked at Wang Yun were somewhat speculative.

Brother He hurriedly said, "He is not from Professor Li, but a researcher at the Mathematics Research Center of Peking University."

The doctor from the National University of Science and Technology was stunned for a moment, "People from the Mathematics Research Center of Peking University, why are you here to join in the fun?" Seeing his puzzled look, Brother He explained, "He is Professor Wan from our Yucheng Mathematics Research Center. I have been invited, and I have passed the approval, and I guarantee that there will be no problem. Isn’t it because we are in a hurry to come here this time, and we need a mathematics researcher who is very familiar with fluid mechanics? The first thing the professor thought of was him, so he gave him directly. Bring it here."

The doctor nodded slightly, "There is such a thing." Then he looked at Wang Yun and said, "A researcher at the Mathematics Research Center of Peking University, so young? What is his background?"

"The champion of the IMO competition, the prover of the new Mason's conjecture, and the latest project is the proof of Zhou's conjecture." Brother He smiled and looked at the doctor.

The doctor was stunned for a while, and then he came back to his senses, looked at Wang Yun and said in a daze, "So awesome?"

"My surname is Ma, you can just call me Ma Bo. I am the leader of this experimental group—" Speaking of this, Ma Bo looked at the laboratory and said, "We are mainly responsible for the data verification of turbulent flow, so The experimental conditions are relatively simple, so you just make do with it.”

When talking about this, Marbo put the chalk in his hand on the podium, looked at the blackboard and said, "No, this is the current data, but something is not quite right."

"No, I remember that there should be six people in our experimental group? Why did you two come here, and there are three more people?" Ma Bo first looked at the data on the blackboard, and all of them recovered, looking at Wang Yun and Brother He, I am a little puzzled.

"Oh, my senior brothers should be here soon."

"Are you familiar with this researcher at Peking University's Institute of Mathematics?" Probably because the experimental team and other personnel have not yet arrived, and Dr. Ma did not let them start work immediately, but chatted with them.

The three randomly found a few seats and sat down. Brother He nodded, "When Xiao Wang was training at Yucheng University, he helped with experiments in our laboratory."

Ma Bo glanced at Wang Yun, "Your name is Xiao Wang, so I will also be called Xiao Wang." Ma Bo showed a sunny smile and said, "So what kind of training team is Xiao Wang?"

"National High School Mathematics Olympiad." Shrugging his shoulders, Brother He said, "It was March, Xiao Wang knows a lot about flow fields and CFD models. And he is very good at mathematics, especially in functional analysis." Absolutely top notch."

"Where's the Fourier transform?" Ma Bo looked at Wang Yun, blinked his eyes, "Xiao Wang, how old are you? IMO champion, you're amazing."

"It will be full in a few days." Wang Yun said with a shy smile, "Brother Ma, you look quite young."

When Wang Yun said that, Brother He remembered that Ma Bo in front of him also looked quite young.

"Mist grass, Brother Ma, how old are you this year, why do you look...so young?" Brother He felt a little wronged, two young geniuses sandwiched him, he was a graduate student who wanted to cry but had no tears!

Ma Bo was stunned for a moment, "I'm 24 this year, so I'm not young anymore."

"I'm already a doctoral student at 24, very good." Wang Yun said with emotion, "Brother Ma must be very good."

"Where, where." Ma Bo gave up, "It's just that the instructor thinks highly of me, I'm a direct blogger." Ma Bo said dumbfounded, "It's not as good as you, mathematics is already so good, and there is still time to study fluid mechanics. I alone CFD has been learned to tears."

"Brother Ma is from the National University of Science and Technology?"

"Yes, it's not as good as your Peking University. Your Peking University has a state key laboratory in the turbulent area." Speaking of this, Ma Bo became curious, "Which college of Peking University do you belong to, the School of Numbers?"

"Yuanpei College." Wang Yun smiled, "I haven't decided which college to study yet."

"That's right. Talent like you should study in Yuanpei Academy."

"Did Ma go to UCAS as an undergraduate or as a graduate student?" Wang Yun was curious about UCAS, after all, it was much more mysterious than other universities.

Except for the discussion with the laboratory, the National University of Science and Technology is almost on its own.

"I studied at the National University of Science and Technology as an undergraduate, and my scores at that time were able to go to Beijing University. They said that I was allowed to study in Yuanpei Academy. I thought that young people should have a little ideal, so I applied to the National University of Science and Technology."

"Boss, big boss!" It turned out to be the champion of the last King of Kings Contest!Brother He cupped his hands and said, why does he feel that he is a little restless now?The two bully kings were sitting next to him, cordially exchanging their experience of pretending to be bully, and he almost wanted to collapse.

I originally thought that becoming a graduate student in a key university is already great, at least—there are not many graduate students in a key university.But in front of the two kings, why does he feel that he has lived on dogs for so many years?

Can you let him change the experimental group and let the two bully kings pretend to be bullying each other?

After chatting here for a while, the other members arrived late.After all the experimental team members arrived, Ma Bo's face suddenly became serious.He stood up, walked up to the podium, looked at the graduate students below and said, "Today is the first day, so I won't bother with you. However, I hope that you can arrive at the laboratory on time in the future, because the experimental task is more urgent, and it is more difficult." Heavy, so, I hope you will not be late again!"

Ma Bo's words were sonorous and powerful, and then he began to arrange tasks.

The rest of the graduate students received their tasks. Ma Bo looked at Wang Yun and said, "Xiao Wang, come here. You are a researcher at the Data Research Center, and you are familiar with the flow field." Having said this, Ma Bo turned around, Looking at the blackboard, he said, "Deduce the turbulence data with me."

"En." Wang Yun nodded, took the chalk, and walked up to the podium.After glancing at the formula on the blackboard, he continued to write without hesitation.

Ma Bo glanced at Wang Yun, nodded, and began to write his own data.

After a while, Wang Yun suddenly stopped writing, looked at Ma Bo and said, "Brother Ma, I feel like there is something wrong with the data."
