I really just want to be a scholar

Chapter 391 Reluctance

Turbulence problems can generally be studied using the standard K-∑ model derived from the Reynolds time-averaged equation, but Qin Ke has obtained several mathematical model ideas that are more effective and clearly described through the S-level knowledge in his mind. At this time, he Mix it together as much as possible, and write in a hurry:

"Combining the Euker method and the Lagrange method, a new type of model is introduced, which I call the 'ELEX' model, which can solve the problem that when different phases are treated as interpenetrating continuous media, the volume occupied by one phase cannot be occupied by other phases. problems of possession, and characterizing the behavior of discrete particles...”

"The modeling of 'ELEX' is based on mathematical methods, as follows:..."

"The verification of the simulation results of the 'ELEX' model can be carried out through the FLUENT software on the computer. The watershed is divided into continuous and non-overlapping structural grids, and the number is set to three levels, which are verified separately..."

The sun was slowly setting to the west, and Qin Ke, holding the sharp weapon of S-level knowledge, was as powerful as a bamboo. In one afternoon, he completed the expression of the nonlinear partial differential equations of the control equation, as well as the establishment of a new model and the export of simulation data.

"Xiaoguang, help me compare the original experimental data with the simulated data." Qin Ke stretched his waist and handed over the subsequent boring data processing to the artificial intelligence Xiaoguang.

Under the guidance of Qin Ke, Ning Qingyun, and Qin Xiaoke respectively, LV2's Shimmer can be regarded as a barely qualified experimental assistant. At least it is capable of data comparison tasks that require a lot of energy, and The efficiency is much higher than that of Qin Ke opening the software for comparison.

Ten minutes later, when Qin Ke had just finished practicing Wing Chun, Shimmer reminded him that the data comparison had been completed.

Qin Ke looked at it in the past and was quite satisfied. The matching rate reached an astonishing 98.22%, far exceeding the industry average of 67.61%.

The model provided in the S-level knowledge is already very perfect, and Qin Ke has carried out creative integration, which has improved the accuracy of the ELEX model at different granularities.

"This detail needs to be optimized."

Qin Ke spent another hour repeatedly modifying and perfecting the ELEX model, increasing the comparison matching degree to 99.17%, which is basically the limit. If you want to optimize it, the time cost is too high. Even if you want to increase it by 0.5%, I'm afraid It is no longer necessary for Qin Ke to spend more than a month supplementing various treatment methods under specific conditions.

With this model, we can adjust the parameters and simulate the experimental results under different parameters. From the best simulated data, we can deduce how to improve the mud-water separation efficiency of the radial flow secondary settling tank, and how to improve the separation efficiency of the radial flow secondary settling tank when the processing load is constant. Under the upgrade, the effluent quality can still be guaranteed to meet the standard and the stable operation of the biological treatment system can prevent the occurrence of sludge denitrification.

This part is very time-consuming and energy-intensive team work.

According to Professor Hu's division of labor, Qin Ke is only responsible for building models and obtaining the best simulated experimental data, and Professor Hu's scientific research team will solve the follow-up.

"It's done. Professor Hu's task is easier than imagined. According to this progress, it can be done in three days."

For Qin Ke, the most important thing is that with the ELEX model and these comparison results, he can already write a paper on computational fluid dynamics, the core of which is his new model ELEX that deals with turbulent flow in low-speed closed environments.

The scientific research progressed very smoothly, and Qin Ke was in a very good mood. After checking that the time was almost up, he left the study room and waited for Ning Qingyun at the gate of Qingmu University.

According to WeChat news, Ning Qingyun and her roommates are already on their way back by taxi...

When Ning Qingjun and her roommates Gu Yanfei, Ximen Hui, and Ren Jianan got out of the taxi parked in front of the school, they saw Qin Ke leaning on the lamppost with a smile on his face. The fresh flowers, in the warm yellow twilight, are romantic and beautiful.

I don't know how many girls passed by and gave Qin Ke their envious attention.

"Wow! Qingyun, your boyfriend is so romantic!" The three roommates booed enviously, Ning Qingyun's face flushed with shame, but her heart was sweet.

Qin Ke stepped forward, smiled and sent flowers, and took the shopping bag from the girl.

Ning Qingjun asked in a low voice: "You... why are you here?"

"I miss you, I think it would be good to see you a second sooner."

Ning Qingyun's face turned even redder, and even her pink neck was stained crimson, but her eyes were full of attachment, and she held Qin Ke's hand tightly.

Qin Ke smiled inwardly, life still needs surprises and a sense of ceremony.For a girlfriend who is worth cherishing for a lifetime, these small details cannot be ignored.

Which girl doesn't like romance and surprises?Ning Qingyun, who is obsessed with studying, is no exception, and this little surprise for herself has a significant effect.

Gu Yanfei shouted: "Squad leader, can you stop abusing us single dogs like this? We are so sour that we have no appetite for dinner. But if you want to invite us to dinner, we can take Qingyun's face and reluctantly agree. .”

Qin Ke smiled and turned his head to the three envious girls and said, "The three of you have occupied my house Qingyun for so long, and I still want to charge you. I won't invite you to dinner, at most, I will call you to my dormitory next time." Three of my beasts, fellowship with you. Farewell."

After finishing speaking, Qin Ke held Ning Qingyun's tender little hand, walked into the campus amidst countless admiring eyes, and walked in the night.

"Why are you being so nice to me all of a sudden?" Ning Qingyun's soft voice was full of cute attachment, her small face was pressed against Qin Ke's arm, how could she be so cold in front of others?

This is a side that will only be revealed when Qin Ke is alone.

Qin Ke smiled: "When will I treat you badly?"

He glanced at the shopping bag in his hand and guessed that it probably contained his birthday present.

Even if Ning Qingyun is away from home, he will always miss him in his heart, and he will know from the WeChat news that he will regularly report where he is and what he is doing.

Qin Ke didn't want to limit her itinerary, but she was willing to share her life with Qin Ke, so that Qin Ke could feel at ease.

Thinking of these details, and thinking that there will be a period of separation, Qin Ke's heart is full of reluctance.

Counting the round-trip time for this trip abroad, I am afraid that I will not see Ning Qingyun for more than ten days.

This is the first time the two have been apart for such a long time since they were officially together.

Ning Qingyun seemed to feel his reluctance, she looked at Qin Ke with a blurred gaze, bit her pink lips, and said softly: "I will catch up soon, and I will definitely follow you wherever you go in the future." I can follow."

Qin Ke stretched out his hand to rub her silky hair, and said softly: "I believe in you, and I will wait for you, don't worry, college life is very precious, enjoy it."

Ning Qingjun obediently enjoyed his pampering action, felt the tenderness between her boyfriend's fingers, suddenly felt hot in her heart, leaned close to his ear, and whispered like a mosquito: "I... I bought a swimsuit... I'll change it to you later to see if it fits..."

Seeing Qin Ke's eyes sparkle suddenly, the red-faced girl panicked inexplicably. She lowered her head shyly: "Either...or next time."

"It's better to hit the sun than to choose a day. It's windy outside, and it seems to be snowing. Let's go back quickly, 'Xiaowo No. [-]' has heating." Qin Ke pulled the girl and rushed back with his heart full of excitement.

It seems that there will be a bright spring scenery ahead.

……

Three days later, Qin Ke handed over the part he was in charge of to Professor Hu. Professor Hu still couldn't believe it: "Is this done?"

Isn't this too fast?Normally, even if he asks the professors from the Department of Mathematical Sciences to assist him, it will take about two weeks. After all, it takes time from data analysis to model building, not to mention the subsequent data comparison and optimal solution verification.

It took Qin Ke only four days!Even Professor Hu, who had a high estimate of Qin Ke, found it unbelievable.

He immediately went to his laboratory and organized people to verify Qin Ke's simulation results. Half a day later, the laboratory sent back exciting news that the experimental results were surprisingly consistent with the simulation data provided by Qin Ke!The matching rate of the comparison results exceeds 99.1%!

After hearing the news, Professor Hu couldn't sit still. He quickly instructed the team to deduce the improvement plan of the secondary sedimentation tank according to the simulation results of Qin Ke's optimal solution, and then directly called Academician Jiang Weixian. The first sentence was Sighing: "I really envy you, Academician Jiang, you have accepted a disciple with unlimited potential... You don't know, the graduate students in my laboratory admire Qin Ke so much..."

After Jiang Weixian listened, he just laughed and cursed: "It's alright, alright, don't think about trying to trick my student, and besides, he's done you such a big favor, why don't you just not show it at all?"

"Hey, with you as a teacher who protects his shortcomings, how dare I let him work for nothing? The [-] project funding is just his reward. This is already the salary of a full professor. I, Lao Hu, do things in a righteous way, right?"

An undergraduate student is paid according to the standard of a full professor, which is really good. Jiang Weixian is satisfied: "How much time and energy did he save you? You still earn money this time!"

After hanging up the phone, Jiang Wei first looked at the phone, shook his head and said with a smile, "This restless kid... But, it seems that I really have someone to succeed me."

Qin Ke soon received the check from Professor Hu in person, which surprised him a lot. He didn't expect to have such a large income.

"By the way, Professor Hu, I would like to borrow your experimental data to write a paper on a mathematical model, is that okay?"

Professor Hu said bluntly: "That's naturally possible. My research topic will only refer to your simulation results, and I don't need to involve the details of the model. But it's best to submit again in the middle of next month, and my project will be completed by then. "

The two sides had a pleasant discussion, and Professor Hu said goodbye after saying that he would ask Qin Ke for help if he had similar problems in the future.

For Qin Ke, the first paper on fluid mechanics required by the system was done.

Before Qin Ke found the data for the second subject, he couldn't write the second and third papers.

Most of the system's tasks have no time limit requirements, so he is not in a hurry, and continues to enjoy the good time with Ning Qingyun, and put his mind back to the Polignac conjecture project that Ning Qingyun was working on together.

At the same time, with the snow covering the world, his 19 years old birthday came as scheduled on Christmas Eve.

There is only one week left before departure to Princeton University.
