Chapter 165 The wonderful 912

Li Mo read it patiently, it turns out that the engine encountered problems during the development process. A mathematical puzzle, “turbulent flow”.

After an aviation rocket is ignited, the interior of the engine is filled with high-energy gas after combustion. How to describe the velocity field and turbulence intensity distribution of the cold gas phase flow in the sudden expansion chamber plays a crucial role in the optimization of the engine mechanism . Because energy is dissipated in turbulent flow.

When Li Mo saw this question, Li Mo felt a big head.

The phenomenon of turbulence is actually very common, rivers bypass stones, coffee mixed with milk, and slowly rising Green smoke. To put it simply, turbulent flow is a large vortex flow containing small vortex flows, but from various scales, it is a temporally disordered but statistically regular motion.

Turbulence is hailed by scientists as the last unsolved problem in classical physics, and it has also become the object of in-depth research by countless physicists and mathematicians in recent years. But so far, no scientist has announced a successful solution to it.

According to legend, the famous theoretical physicist Werner Heisenberg once said a sentence before his death, “When I see God, I must ask him two questions – what is the theory of relativity, What is turbulence? I believe he should only have an answer to the first question.”

The fundamental reason is that there are too many unknown factors in turbulence. Known conditions infer unknown results, but when there are too many unknowns, this tool is not so useful.

At this time, it is necessary to establish a mathematical model to “fuzzily” solve this problem.

“How is it, do you have the confidence to solve it?” Wang Lao asked eagerly when he saw Li Mo frowning.

Li Mo thought for a while and replied: “The 912 members who designed the engine must have tried it. In fact, for this kind of problem, there is no solution at all, and one can only get a mathematical model. The optimal solution.”

Wang Lao nodded: “He did try it, but the mathematical model he made is far from the data obtained in the actual experiment. So please find someone who can solve the problem. The person who solves this problem.”

“I think the person who can solve this problem is you.”

Li Mo felt like a donkey with a collar around his neck, Wang Lao’s words are whips.

Seeing that he was hesitating, Mr. Wang said with a serious face: “I know it’s really hard for you to be a mathematician to do this kind of theoretical physics.”

” Due to confidentiality reasons, it is not convenient for me to tell you the specific situation, but this mathematical model is related to the new generation of launch vehicle plans.”

“Now we are about to enter the space age, and controlling space is equivalent to controlling the world. All countries are also gearing up. Due to our late start, my country has made great achievements in exploring space in recent years, but it is far from enough.”

“Rocket engines play an important role in the space age. , so the country took precautions and started a new plan. Now this plan has encountered difficulties.”

“What I want to ask is, can you top it!”

Wang Lao’s words Like a hammer hitting his heart, is it because of difficulties that one thing is not done?

Li Mo got up from the chair, “Please leave this task to me, I will do my best to complete it.”

In the red flag car, Li Mo looked at the green farmland outside through the car window, and regretted for a while: “Why did I agree?”

everyone has their own field of specialisation, especially in this high-end academic field, Problems can’t be solved with just a little blood. He is really not sure about this kind of turbulence.

“Jiang is still old and hot. Wang Lao’s remarks made him boast about Haikou.” He now knows why Wang Lao is regarded as the older generation of scientists.

Under Wang Lao’s “flickering”, Li Mo decided to go to the studio of the 912 member to find out the specific data.

Unconsciously, the Hongqi car drove on a rugged mountain road. Even if Hai Ge’s driving skills were very high, he still felt very bumpy.

“How far is it?” Li Mo felt his stomach churning.

Brother Hai steered the steering wheel and carefully avoided the stones on the side of the road, “It will be there soon.”

“Who would set up the studio in such a remote place? Don’t you understand the reason why Da Yin is hidden from the world?” Li Mo muttered in his heart, according to the current level of technology, even if it is hidden in a remote place, it will be discovered by the satellites in the sky, it is better to be among the crowd.

“That’s a freak, too.” He looked out the window at the wilderness, already defining the 912 member.

The red flag car slowly stopped.

“Here it is.” Higo pulled the handbrake.

Li Mo got out of the car, watching the scene in front of him in silence.

Because there was nothing in front of him, no people, no houses, no traces of artificiality.

Is it underground? He looked at his feet, stamped a few times, and determined that it was hard ground.

Brother Hai came to a stone wall full of climbing Mountain Tiger, took out a card from his pocket, and swiped it in the corner.

On the stone wall, a stone gate opened silently, and bright lights came from inside.

“I’m fine!”

Looking at the “magic appearance” exit in front of him, Li Mo has a new understanding of this wonderful 912 member.

“Put your headgear on.” Brother Hai took out a black headgear from somewhere and handed it over.

After putting it on, Li Mo found that there were just two small holes in the front of the headgear, allowing him to see the road ahead clearly.

“It’s not allowed to take it off in the cave.” Brother Hai sorted it out for him and made sure to cover it up completely.

Li Mo nods.

The stone gate is not big and can only accommodate one person to pass through. He follows behind Hai Ge.

Passing through the stone gate, you will suddenly see the light, which is a cave with a height of more than 6 meters. There were still tracks on the ground of the cave, and Li Mo knew it must be an abandoned train tunnel.

“He must be a rat.” Li Mo gave a new definition.

Dim streetlights hung from the walls of the tunnel, and he had to cautiously.

“912611?” A voice came along with the sound of bullets being loaded.

Brother Hai stopped and responded, “912166!” Hearing the voice, the other party seemed to put away his weapon.

Turning around, “It’s okay, it’s a defender.”

“Well, it seems that this wonderful 912 is also afraid of death.” Li Mo thought to himself.

From time to time, water droplets dripped from the top of his head and fell on him. The surroundings were silent, and only the footsteps of the two could be heard.

Just when he couldn’t help but was about to stop Brother Hai in front of him.

“Haizi, who did you bring today?” A loud voice came from a side hole next to it.

“Here, remember that you can’t let him know your name.” Brother Hai turned his head and spoke seriously.

Li Mo looked at the black hole, nodded.
