Chapter 29 Physical Chemistry Fluid Mechanics(1/2)
Soon, ten days will pass!
At 7:50 in the morning of the eleventh day, everyone gathered in their respective classrooms.
"Zhuoyue, I heard you were the school beauties of Peking University?" Sitting next to Zhuoyue was a student from Jiang University named Cui Chengwu. He looked at Zhuoyue with a gossip.
"It's nothing, we just chat occasionally." Zhuoyue glanced around and saw several people looking at him. He said guiltily.
"Don't pretend." Cui Chengwu smiled and said, "Everyone who we come to train knows about this."
"Do you all know?" Zhuo Yue said in a daze, feeling his voice a little loud, which caused more people to look at him. He quickly approached Cui Chengwu's ear and lowered his voice, "How come you all know?"
"It was Ren Hang who told me."
Ren Hang is another student who came to Jiang Dalai to train.
"How did Ren Hang know?" Zhuo Yue asked.
"Ren Hang listened to Xi Xin."
"Fuck." Zhuo Yue cursed angrily, "Xi Xin's big mouth."
"You really got the school beauties of Peking University?" Cui Chengwu looked at Zhuoyue in surprise.
Then he patted Zhuoyue on the shoulder repeatedly and smiled, "Brother, yes, you have only been here for a few days and got the school beauties of Peking University. It really makes us, the people who come to Peking University for training!"
"It's nothing, we are just ordinary friends. Don't talk nonsense and ruin the reputation of other girls." Zhuoyue said anxiously.
"Haha..." Cui Chengwu laughed and said, "I understand, I understand, ordinary friends? Don't lovers start with ordinary friends!"
"Why don't you believe me!" Zhuoyue said helplessly: "I am a person who will fight on the road of science all my life, and women will only stop me from moving forward."
Cui Chengwu looked at him with contempt. You have hooked up the school beauty and are still pretending to be pure for me.
"Hey..." Seeing that Cui Chengwu still didn't believe him, Zhuo Yue sighed helplessly.
A moment later, Professor Yao Shizhen walked in.
Everyone stopped chatting, sat up on the table and looked at Professor Yao.
Yao's classroom stood on the podium, glanced at everyone, and said, "I have heard a lot of rumors about you during this period, and the most common ones was that someone had soaked the school beauties of Peking University."
"Hahaha..." Everyone looked at Zhuoyue with a laugh.
Zhuoyue lowered his head in embarrassment. Now he couldn't even clear his mind even if he jumped into the Yellow River. It was obvious that things were not what you thought, but you had to think about it.
"It's okay to fall in love, but don't delay your studies." Professor Yao smiled and said, "Are you an outstanding classmate?"
"Teacher!" Zhuoyue stood up and said helplessly: "It's not what you think. I'm not in love."
"Young man, do it, don't refuse to admit it!"
"Okay, sit down!" Professor Yao continued to speak without waiting for Zhuoyue, and said, "Let's start the class now."
"In physics, mechanics is the easiest, the most difficult, and the most common."
"We first came into contact with physics, which was classical mechanics."
"Classic mechanics has many different theoretical expressions, the common ones include Newtonian mechanics, Gralange mechanics and Hamiltonian mechanics..."
"The three major branches of classical mechanics are solid mechanics, fluid mechanics and general mechanics. Now let's review solid mechanics..."
The pace of class was very fast. First, I verbally reviewed the three major branches of classical mechanics, and described many relatively rare questions and what kind of theories to solve them.
"I am worthy of being a famous physicist!" Zhuo Yue said in his heart.
The professor gave him a lot of knowledge and ideas on physics, which are all knowledge that is not in books, and are the knowledge summarized by the professor himself after years of studying theoretical physics.
"In classical mechanics, fluid mechanics is the most difficult. It mainly studies the interaction and flow laws when there is relative movement between the fluid and the solid boundary wall under the action of various forces."
“…”
"Fluid mechanics has many branches, and the representative ones are hydrodynamics, gas dynamics, aerodynamics, viscous fluid mechanics, and suspension mechanics..."
"The n-s equation is the theoretical basis of fluid dynamics, and the n-s equation is a set of nonlinear partial differential equations. It is very difficult to study fluid motion using analytical methods."
"In order to simplify the equation, the assumption that the fluid is incompressible and non-viscosity is adopted, but the Dalamborde paradox that goes against the facts is obtained - the resistance of an object when it moves in the fluid is equal to zero."
“…”
"Hmm? Zhuoyue, what are you doing?" The professor suddenly stopped giving a lecture and frowned slightly at Zhuoyue.
"Ah?" Zhuo Yue looked up at him in a daze, put down his pen and said, "Teacher, I am studying the n-s equation!"
"Hu..." Everyone looked at him in shock.
Are you capable of studying n-s equations?
For more than a hundred years, countless scientists have studied n-s equations, but no one has yet to study them.
If you can do it, you won’t come to participate in the training. Wait for the Nobel Prize in Physics!
Professor Yao laughed furiously and waved to him, "Come on, come on, come on, you can study the n-s equation. It seems that fluid mechanics is not difficult for you. If you can explain it well, you don't have to learn fluid mechanics, which can allow you to move freely."
"Teacher, this is not good!" Zhuoyue glanced at everyone in embarrassment and said, "Everyone is studying, I am playing outside, and this has a bad impact."
Everyone was speechless when they heard it, as if fluid mechanics were not difficult for you.
Really show-off!
"It has no effect. In our training, classical mechanics accounts for 70% of all courses, while fluid mechanics accounts for 50% of all courses, and solid mechanics accounts for 20% of all courses, including dielectric mechanics, thermodynamics, statistical mechanics, electrodynamics, relativity and quantum mechanics, each accounting for 50% of all courses."
"If anyone knows a certain part of your knowledge, I will randomly select a certain part of it for you to talk about. If what you are talking about is only a few points worse than me, I will be considered as you pass the test. No need to learn the knowledge you are talking about. When I talk about this part of your knowledge, you can move freely."
Zhuoyue calculated in his mind that if he talked about fluid mechanics, he would have a few days of free time, and he could do other things in this free time.
"Zhuoyue, are you going to try it?" Professor Yao looked at Zhuoyue and asked.
"certainly!"
After saying that, Zhuoyue stood up and walked towards the podium.
"He really went up? Is it okay?" All the students were talking.
"It's definitely not possible. Isn't it a waste of time for him to say this?"
"We are all undergraduates, and we all learn theoretical physics. He is not much stronger than us!"
"Wait and see the joke!"
"Excellence is embarrassing!"
“…”
"Quiet!" Professor Yao looked at everyone and scolded.
Then he moved away from the podium and looked at Zhuoyue and said, "I don't make things difficult for you, just talk about physics, chemistry, fluid mechanics."
Zhuoyue rolled his eyes in his heart. It was said that he was not embarrassed by me. Physics and chemistry fluid mechanics is a very difficult branch of fluid mechanics.
It is often used in industrial construction and national defense construction, such as rockets and missiles...
"Cough..." Zhuo Yue coughed lightly, attracting everyone's gaze.
This is not the first time he has been a teacher, so he is not nervous at all at this time.
He said: "Physical and chemical fluid mechanics are mainly divided into combustion chemical fluid mechanics, diffusion kinetics, electrochemical fluid mechanics, capillary flow kinetics, physical and chemical fluid mechanics in chemical reactors, reaction boundary layer and basic research on physical and chemical fluid mechanics."
"First of all, the combustion chemical fluid mechanics, which are divided into laminar combustion theory, turbulent combustion theory, combustion oscillation, two-phase combustion and mathematical model of combustion chambers and amplification of combustion chambers."
"First I will talk about the laminar combustion theory. Combustion in laminar flow state is the earliest research..."
Excellent pick up the chalk and write on the blackboard: "According to the assumption, the basic continuous equation: ρpup=ρ∞u∞=const
Ignore the viscous force and volumetric force, the momentum equation is: ppρpu2p=p∞ρ∞u2∞=const(p is all subscripted)
...
The above formula is the Hugo nit equation and the body gongnu curve."
Professor Yao, who was standing aside, stared at Zhuoyue, as if he saw a ghost, almost pulled his eyes off in surprise.
"Zhaoyue actually knows the Hugo Niet equation. Only those engaged in military scientific research know about it. How could he know about it?"
The students below were fascinated by the hearing before they knew it, forgot their outstanding identity, and thought that a professor was giving them a lecture.
After a long time, Zhuoyue stopped giving a lecture and threw away the chalk in his hand, "That's all about physics, chemistry, fluid mechanics."
After saying that, he looked at Professor Yao and said, "Teacher, have I passed the test?"
"Ah?" Professor Yao looked at him blankly, then reacted and said repeatedly: "I passed the test, I passed the test."
Only then did all the students wake up from their outstanding lectures regretfully, and then they talked enthusiastically.
"This is actually what Zhuoyue said. How could he know so much knowledge? He knows more than us!"
"I thought it was a professor who taught us."
"I think so too. I feel that he is no worse than the professor in physics, chemistry, fluid mechanics."
"I think so too."
“…”
Wei Jing looked at Zhuoyue in shock, and then smiled bitterly in his heart, "I didn't expect that Zhejiang University would have students like Zhuoyue. As expected, we can't underestimate anyone. There are many geniuses that have not been discovered by the junior class."
