don't call me singer

Chapter 488 Like a Whale Singing (Addition 715 for [Frozen] Ruthless)

"30 meters below us, there is a pump-jet propeller. My job is to improve its working noise, enhance its energy efficiency, and enhance its reliability..." Pan Guoxiang introduced, "We are conducting preliminary tests here. Then, if it passes the early experiments, it will be taken to drag pools and water holes for more complex follow-up studies..."

"Because my work involves some confidentiality, I won't show you the relevant materials and models..." Pan Guoxiang saw Gu Xiaobai's curious face, and cut off his thoughts mercilessly, "But Xiaobai You should understand that my work is very important, so I have no time and no way to cooperate with you."

Next to him, the director who accompanied the visit glared at him, can you speak!

Your work is important, but other people's work is not important?

Of course, in fact, the scientific community also has a chain of contempt, but the chain of contempt in the scientific community is not very regular.

Many people think that their work is very important, and other people's work is a piece of shit.

For example, now, Pan Guoxiang views Gu Xiaobai in this way.

Of course, for the director, the research that can afford food is important research.

Now the landlord's family has no surplus food, and it is hard to find funds.

Gu Xiaobai said: "Can you open it for me to see?"

"This is fine." Before Pan Guoxiang could say anything, the director waved his hand.

The propeller was hidden 30 meters below the water, so they couldn't see it, and they couldn't even hear it. That's why they didn't care about Gu Xiaobai's visit.

After all, Gu Xiaobai is not a cat or a dog. He is also a top expert in the field of acoustic subdivision. Although the work is confidential, communication in the industry is also necessary, otherwise it will be behind closed doors.

A student next to him rushed away immediately, and after a while, the water surface began to fluctuate slightly.

The 30 meters of water basically covered up all the sounds, only the slight sound of water reverberating could be heard.

Gu Xiaobai lowered his head, looked down seriously, and listened attentively.

Pan Guoxiang felt a little funny seeing his serious attitude.

With such a long distance and a 30-meter-thick water layer, it's no wonder you can hear anything!

Moreover, many of the noises produced by these underwater propellers are infrasound waves and ultrasonic waves, which far exceed the limit of human hearing, and it is impossible for human ears to hear them.

He said to Gu Xiaobai: "This is what we are doing. It belongs to the category of fluid mechanics and hydroacoustics. Xiaobai, you are studying musical instrument acoustics and atmospheric acoustics. Have you studied fluid mechanics and hydroacoustics? Personally, I suggest, Xiaobai, you still need to learn some knowledge of fluid mechanics. I personally think that acoustics is a subset of fluid mechanics. In the physical process of fluid mechanics research, there are energy exchange, transfer, and mass exchange, but the main focus is on Research on quality. In the physical process of acoustic research, there is only energy transfer and exchange, but no mass exchange. It focuses on the study of the acoustic energy field. The theories of the two disciplines have certain similarities. The theory of mechanics can also solve some acoustic problems, so Xiaobai, if you want to make achievements in acoustics, you must also study fluid mechanics, why not come and be my graduate student..."

The more Pan Guoxiang talked, the happier he was, and it seemed to be pointing the country, but the complexion of the director next to him was getting worse and worse.

What do you mean, that acoustics is a subset of your fluid mechanics?Is this belittling someone else's acoustic research?And if you let someone else be your graduate student, do you really not treat the other person as an equivalent scholar, or do you still treat the other person as a student?

Gu Xiaobai nodded and said: "That's right, fluid mechanics and acoustics are still related. Fluid mechanics is a branch of mechanics, and acoustics is one of the five basic disciplines of physics: mechanics, thermals, acoustics, optics, and electricity. Say, acoustics can be said to be the uncle of fluid mechanics..."

Pan Guoxiang's face turned dark after "brushing".

Who do you say is uncle?
Boy, I think you want to rebel?

"Your statement is wrong. Acoustics should definitely be subject to fluid mechanics. Although acoustics is self-contained in solving specific problems, it is nothing more than simplifying basic equations and more specific descriptions. Using mathematical tools All the same, you should try to use fluid mechanics, solid mechanics, and fluid-structure interaction to do acoustics, so that..."

Next to him, Pan Guoxiang's students raised their quota with their hands. Is the teacher arguing with Xiaobai?

Why can the teacher quarrel with anyone!
Teacher, please look up at Xiaobai's handsome and shining face!How can you have the heart to quarrel with Xiaobai!
Wait, did the teacher secretly take off his glasses?
Is this highly myopic man now facing a fuzzy luminous body?Otherwise, how can you have enough courage?

"Mr. Pan, you are right. Fluid mechanics and acoustics are indeed common in many aspects, but this cannot be changed. In fact, many aspects of fluid mechanics are derived from the facts of acoustic research... But what you said is using fluid mechanics to solve acoustic problems. The idea, I think it should be feasible, you can try it.”

Saying that, Gu Xiaobai closed his eyes.

At that moment, the flow of time around him seemed to stand still for an instant.

Gu Xiaobai's consciousness entered his own memory palace, and time was slowed down countless times. In the huge "music room" like a factory building, there was smoke and endless streamers flickering, and Gu Xiaobai was slowly emerging from it. The huge factory-like laboratory where Xiaobai is at this moment.

Tall metal supports, deep pool water...

Everything is the same as the outside world.

The "mv system" given to Gu Xiaobai by the system is actually the most powerful simulator in the world.

It can be fully recorded and intercepted, a real time and space.

Gu Xiaobai stretched out his hand and gently swiped upwards, as if there was an invisible big hand that moved the space instantly.

In the next second, Gu Xiaobai sank into the water, and in front of him, a huge, rapidly rotating pump jet propeller appeared.

Gu Xiaobai gently closed his hands, and the propeller and pool shrank instantly, turning into a plaything in Gu Xiaobai's palm, similar to a wave maker in a fish tank.

And Gu Xiaobai observed this for a while, and when he pulled his hands outward, the thruster was enlarged to infinity. In front of Gu Xiaobai, there were tiny cavitation bubbles generated by the tip of the propeller blades, which were produced and then burst...

The slowly rotating propeller is like a huge black hole that can suck in the entire earth.

Behind the black hole, a dark mass was staring at Gu Xiaobai unhappily.

This system gives you the MV system, you don't shoot MV, you use it to study physics all day long!
How many monthly tickets does physics give you!Why are you doing this!

Gu Xiaobai was a little embarrassed to be stared at by the system like this, and said with a smile: "Well, I'm actually studying musical instruments..."

"You just imagine this big rotating propeller as a huge musical instrument that can be used in water. Now we want to make it as quiet as possible and make less noise..."

The system stared at Gu Xiaobai, "Pooh, I don't read much, don't lie to me!"

"Anyway, that's how it is..." Gu Xiaobai spread his hands, "There's nothing you can do if you don't believe it..."

The water flow passed the pump jet, sprayed on Gu Xiaobai's body, passed through his body, and flowed behind Gu Xiaobai.

Gu Xiaobai's body seems to be semi-solid in this space, and every part of his skin can feel the changes of the water flow.

Human beings cannot hear ultrasonic and infrasound waves, but this does not mean that human beings cannot feel the pressure changes they bring.

But now, Gu Xiaobai obviously turned his body into this kind of receptor.

Gu Xiaobai's consciousness is actually completely connected to this space. Under his control, the water flowed into silk threads with different colors, but never intertwined with each other, passing through Gu Xiaobai's body.

But the sound turned into countless transparent arrows of different thicknesses, radiating in all directions.

He stretched out his hand, and the paddle was changing slightly with his fingers, length and width, shape, thickness...

The threads and arrows are also constantly changing.

And for a moment, it seemed that all the noise was canceled out and suppressed, and a constant sound wave came out under the background noise that was reduced to a very low level.

"Huh?" Gu Xiaobai's eyes lit up.

He controlled the blade to change slowly, and the tone also changed slowly.

Next to him, the dark little Hei looked at a loss, is this thing really a musical instrument?
It seems to be quite fun.

Sure enough, I knew that my host couldn't be so ruthless, using my system to study physics!
Gu Xiaobai opened his eyes, and the people around him looked at him wonderingly, wondering why he suddenly closed his eyes.

"Do you have CFD software?" Gu Xiaobai asked a student next to him.

"Of course there is." How can anyone who studies fluid mechanics not have CFD software?

"Then you guys try this later." Gu Xiaobai took out a pen and paper, and began to write.

A long formula, and a long list of parameters behind it.

"Thank you for allowing me to visit, I should go back and prepare for the tour." Gu Xiaobai bowed to them again, "Thank you teachers, brothers and sisters."

Is this gone?

The director sent Gu Xiaobai away, with a look of disappointment on his face, complaining to Pan Guoxiang: "You must be too blunt to make Xiaobai angry, and there are several hundred of us, and we need to have just the right meal, just the right meal... ..."

Pan Guoxiang did not speak. When he returned to the laboratory, he heard the students calling him: "Teacher, teacher, come quickly!"

"Teacher, listen!" The person who called him was a student who claimed to be Jiangcheng 306. They were sitting in front of the computer, manipulating the simulation software, and humming softly along with the deep voice floating in the air:
"Hmph, I'm angry, I'm angry..."

Pan Guoxiang looked blank, what the hell, did you ask me to come over just to let me hear you sing "Humph, I'm Angry"?

If you do this again, I'm really going to be angry!
Just before he got angry, Wang Haixia of Jiangcheng hurriedly said: "Teacher, this is the formula and parameters left by Xiaobai just now! It's a music score, hahahaha, it's actually a music score!"

Next to it, two female students looked intoxicated: "What a beautiful voice... like a whale singing, is this Xiaobai singing for us?"

sheet music?

Use the turbulent noise of the pump spray as an instrument to play music?
Can this kid stop being so unprofessional! ! ! ! ! !

Destroy the gods, despise the gods!

Wouldn't it be good to use your talent to benefit the country and the people? ! ! ! !

Pan Guoxiang was so angry that he was about to leave, but suddenly he was shocked.

Wait, formulas and parameters?

He lowered his head, grabbed the piece of paper next to him, glanced at the formula, and then repeated it silently several times in his heart, his complexion slowly changed.

The student next to him heard Pan Guoxiang's "hiss—" and took a long, long breath of air.

Ah, such a long air-conditioning, it sounds painful!
The teacher's kidney stones are really coming on fiercely today!

"Teacher, drink more water!"
