Let you take charge of the military academy, the world's number one university?

Editorial Board of Nature.

Bruce is an academic editor of natural science journals and a graduate of the Massachusetts Institute of Technology.

His daily job is to browse through submissions from all over the world, select high-quality papers for reviewers.

But......

Bruce has been depressed lately.

There are a lot of papers in the mailbox.

But there are few high-quality papers.

The key "Nature" natural science journal is a weekly issue.

The academic editors within the journal have monthly paper indicators.

If he fails to submit a high-quality paper this month, he will definitely be scolded by the editor-in-chief.

Bruce patiently scanned the papers in his mailbox and muttered, "This one can't work, this one can't work..."

Flip through the room.

He was suddenly attracted to a paper called "Structural Calculations for Turbulence."

Bruce looked at the paper intently, his eyes getting brighter and brighter.

In the content of the paper.

The author, Cheng Ziyue, first elaborated on the energy gradient theory in physics.

This theory is used to study flow stability and turbulent transition.

It is found that in the rotary flow, the mechanical energy gradient along the streamline normal direction in the flow field plays an unstable role on the flow, and the mechanical energy gradient along the streamline direction plays a stabilizing effect on the flow, and the stability of the flow depends on the ratio of these two quantities, this ratio is - an undependent variable, defined as an energy gradient function, and its physical meaning is - a local Reynolds number.

The occurrence of turbulence rotation depends on the magnitude of the energy gradient function in the flow field and the unaffected amplitude of the disturbance.

Under the action of unsteady perturbation, when the vector direction of the total mechanical energy gradient at a certain location in the flow field is perpendicular to the velocity vector, the value of the energy gradient function at 07 becomes infinity, and this point becomes the singularity of the Naver-Stokes equation.

At this singularity location, the velocity of the flow direction abruptly changes to zero, the velocity occurs at the tip, and the pressure produces a peak.

In fact, this is the beginning of turbulence.

After the paper was presented.

Cheng Ziyue began to test this theory.

She used theoretical predictions of flow field changes to be consistent with experimental results to determine the "burst" site of turbulence.

Then, she used Poisson equation analysis to prove again that the point where the mechanical energy gradient and the velocity vector are perpendicular to each other is a singularity in the flow field.

Pass rigorous mathematical proof.

The results show that the necessary and sufficient condition for turbulence generation is the singularity of the Naver-Stokes equation in the flow field.

Turbulence is caused by nonlinear instability caused by singularities caused by velocity interruptions in the flow field.

The occurrence of turbulence depends entirely on the magnitude and direction of the mechanical energy gradient in the flow field.

The change of Reynolds number Re in Newtonian flow and the change of Deborah number De in non-Newtonian flow have a role in turbulent flow rotation and affect the change of mechanical energy gradient.

The theoretical analysis results are consistent with a large number of experimental results and direct numerical simulation results of the Navier-Stokes equation.

Cheng Ziyue's definition of turbulence is the most stable dynamic dynamic state of a fluid governed by mechanical energy gradients.

The maintenance of turbulence is achieved by the continuous nonlinear instability of a large number of singularities in the flow field.

If under the influence of certain conditions.

For example, by lowering the Reynolds number, the nonlinear instability caused by the singularity of the Navier-Stokes equation in the flow field gradually disappears, and the turbulence becomes laminar.

In the content of the paper.

Cheng Ziyue introduced the mystery of turbulence in detail in an in-depth way.

Her theory, which subverts the original turbulence theory, is a new turbulence theory system, and is the original innovative work of "from 0 to 1".

Under this completely new theory.

All the secrets related to turbulence are on paper.

Under thousands of systems of differential equations and various formulas.

The internal structure of turbulence was clearly calculated by Cheng Ziyue in the form of a serious formula.

......

See here.

Bruce marveled.

He had a Ph.D. in physics at the Massachusetts Institute of Technology and was well aware of the implications behind the turbulence problem.

The turbulence problem, which cannot be accurately expressed and predicted through mathematical language, is known as the last unsolved problem of classical mechanics.

In physics, there is a poem about turbulence.

"The big whirlpool breeds the small whirlpool with kinetic energy, and the small whirlpool also conceives children from this to the end of life, and the life has changed, and finally disappears into stickiness."

If the turbulence problem can be solved.

Not only the progress in the field of fluid mechanics, but also the progress in the field of physics, mathematics, and even human science and technology!

And now...

Cheng Ziyue, the author of the paper, completely solved the turbulence problem, which means that all the problems of classical mechanics have been overcome!

Bruce glanced at Cheng Ziyue's school: The-Blue-Sky-Military-University.

He was stunned.

Blue Sky Military University?

How come you've never heard of this university before?

Bruce opened the search engine and searched for the name of the school, only to suddenly realize.

Blue Sky Military University is a military college located in Qindao City, Xia Guo Shandong Province.

After the paper is checked.

He passed the preliminary review of the paper at the first time and sent the paper to the four reviewers of the natural science journal of Nature for review.

Papers belong to the field of physical sciences and need to be cross-reviewed by the big bulls in the field.

......

Mid-January.

Nature journal is published.

As soon as the journal was released, it attracted widespread attention from the academic community.

Xia Guo student circle.

When physicists saw the headlines on the cover of the journal, they were taken aback.

I saw that the title of the cover reads "Nature: Cheng Ziyue solves the turbulence problem and overcomes the last problem of classical mechanics!" 》。

The scientists hurriedly clicked into the paper to watch the detailed content.

After reading the whole paper.

They were all amazed.

Cheng Ziyue, a sophomore at Blue Sky Military University, is so talented that she can solve the turbulence problem that countless scientists are powerless to.

It's also incredible!

One pass ten pass under a hundred. (Read violent novels, just go to Feilu Fiction Network!) ）

The news that Cheng Ziyue solved the turbulence problem swept the entire academic community in an instant.

Physicists from all over the world learned that the author of the paper, Cheng Ziyue, was only 19 years old this year, and they all lamented that heroes were teenagers.

Xia Guo Blue Sky Military University, born a real physics genius!

......

At the same time.

The major news media at home and abroad are all news that the turbulence problem has been solved.

"19-year-old genius girl, Cheng Ziyue conquered two hundred years of scientific problems!" 》

"Blue Sky Student Cheng Ziyue, a female scientist of Xia Guo who shocked the world!" 》

"Blue sky student against the sky, Cheng Ziyue interprets the scarf and does not let the eyebrows! 》

The turbulence problem is solved! Cheng Ziyue overcomes the final problem of classical physics! 》

"A new era of physics is coming, Blue Sky Military Academy student Cheng Ziyue creates miracles!" 》

Future Nobel Prize winners in physics! Cheng Ziyue made the physics community crazy! 》

"The problem of the mechanics world was solved, and the MIT professor cheered: Cheng Ziyue opened the door to a new world for the physics world!" 》

Science Person of the Year 2015! Cheng Ziyue, a sophomore at Blue Sky Military University, was named the first scientific figure of the year in the Nature Journal! 》

......

It was late that day.

Xia Guo's news program devoted three minutes to introducing the problem of turbulence being overcome.

Host Kang Hui, broadcast report: "The flow of human beings creates society, the flow of products brings commerce, the flow of money brings civilization, the flow of ideas brings civilization, and the flow of blood sustains life."

The irregular flow of the fluid medium creates turbulence.

In the field of physics, the mystery of turbulence has been unsolved, allowing countless scientists to follow.

Recently, Cheng Ziyue, a 19-year-old female student at Blue Sky Military University, calculated the internal structure of turbulence with a serious formula and completely solved the mystery of turbulence.

After the mystery of turbulence is solved, it will usher in a new leap in the fields of aviation, aerospace, shipbuilding, power, water conservancy, chemical industry, marine engineering, meteorology, marine science, astronomy and enter a new round of industrial revolution..."

......

The camera turns.

Cheng Ziyue is being interviewed by reporters.

The female reporter asked: "Student Cheng, there are fewer and fewer scientists engaged in the field of turbulence, why are you interested in turbulence?" "

"I'm interested in physics!"

Cheng Ziyue said with a smile: "In fact, every physicist is interested in turbulence, but it is too difficult to break through.

As a result, there are fewer and fewer scientists studying the field of turbulence.

After all, academia, if it has not achieved results, how can it support its family?

And I am still a student, there is no pressure to provide for my family.

In addition, I was the champion of the Blue Sky Military University intramural physics competition for two consecutive years, and I won a high prize.

Compared to other students, I don't have to worry about living expenses, there is no pressure.

Maybe it's this relaxed atmosphere.

I can study more undistractedly and shine in my favorite field! "

Hear this.

The female reporter nodded.

Turbulence problems, nominally physical problems, are actually physiological and psychological problems.

She asked: "Cheng 047, now that the turbulence field has been conquered, what kind of follow-up changes do you think will occur?" "

Cheng Ziyue said bluntly: "Turbulence has become one of the key bottlenecks affecting the success or failure of national aerospace and navigation projects, and it is a major application basic topic that the country urgently needs to solve."

At present, there are turbulence laboratory of Blue Sky Military University, turbulence laboratory of Yenching University, turbulence laboratory of Huaqing University, turbulence laboratory of Zhejiang University, turbulence laboratory of Harbin Institute of Technology and so on.

As the mystery of turbulence is solved.

This will make turbulence a frontier hot issue in theoretical physics research.

The next few years.

There will be a lot of flowers in the physics world! "

The reporter finally asked: "Student Cheng, you have overcome the turbulence problem, and your achievements have been recognized and respected by the world.

You can apply to any school for graduate school, not even graduate students, direct postdocs or professors.

You may also become an academician of the Xia Guo Academy of Sciences and even win the Nobel Prize in Physics.

I would like to ask, what are your personal plans for the next step? "

"Study hard and go up every day!"

Cheng Ziyue said with a solemn expression: "The more I come into contact with the field of physics, the more I feel that my knowledge is not enough.

In fact, this time I was able to overcome the turbulence problem.

The supercomputer of Blue Sky Military University helped me a lot.

In that regard, I would like to thank the school.

The rest of my college career.

I will continue to work hard to produce more heavyweight results and become a student that the school is proud of! "

......

After the Xia Guo news program ended.

The entire Internet is talking about Cheng Ziyue.

"Oh my God! Cheng Ziyue became a god in a battle! "

"Cheng Ziyue has already ranked among the top physicists!"

"After the mystery of turbulence is solved, our Xia Kingdom can step on a new level in the industrial field!"

"There are talented people in Jiangshan generation! Thank you Blue Sky Military University for training us a genius scientist! "

"With her current achievements alone, Cheng Ziyue can become an academician and win top awards such as the Nobel Prize in Physics, the Wolf Prize in Physics, the Einstein World Science Prize, and the Dirac Medal."

"Blue Sky Military University is really powerful, and its ability to cultivate talents is ridiculously strong!"

"That's right! They have not only cultivated a large number of world champions, but also cultivated geniuses like Cheng Ziyue, which is worthy of being a well-known military academy in China! "。
