Back at the group headquarters, as soon as Zhou Yan sat down, Chu Xinyang entered the office with a smile.
"Mr. Zhou..." Chu Xinyang had a flattering smile on his face, which made Zhou Yan frown.
"If you have something to say..."
"Mr. Zhou, people like Chaoyue have started to make electric vehicles. Do you think you can come to our design department to work for a while..."
"At this stage, all the information I can think of is available in Zhengxin's data server!" Zhou Yan gave Chu Xinyang a slap in the face.
"But this electric car is a new concept..."
"What the hell, for safety reasons, the position of the battery is fixed, and the position of the motor is also fixed. The only thing left is the aerodynamic shape, and there is still a certain amount of operating space..."
As he spoke, Zhou Yan suddenly remembered that the equation he wrote about N-S had been published in a top publication.
"You kid, let me design the shape of your electric car, right?"
"Hehe..." Chu Xinyang just giggled, acquiescing.
"It's the end of the year, and it's impossible to work for you, but..." Zhou Yan thought for a while, "I can provide new aerodynamic shape design ideas..."
"What idea?" The smile on Chu Xinyang's face disappeared and he stared at Zhou Yan seriously.
"Traditional car shape design generally involves drawing up a rough aerodynamic shape first, then constantly revising it, and then reaching a compromise between minimum wind resistance and design, right?"
"Yes!"
"We can call it active aerodynamic shape design." Zhou Yan looked at Chu Xinyang who had frowned with a smile, "My new idea is passive aerodynamic shape design."
"Passive?" Chu Xinyang was still a little confused.
"When designing the shape of a car, leave the work to the wind..."
"What's more specific?" Chu Xinyang's eyes lit up.
"To be precise, when making a model, non-modifiable hardware such as the engine is made of non-plastic materials, while the peripheral space is filled with materials with relatively high plasticity. The model is then placed in a wind tunnel and the flowing air shapes the shape of the car.
…”
Chu Xinyang felt that something in his heart was broken, and the door to a new world opened...
"In this way..." Chu Xinyang's eyebrows were full of joy, "Actually, part of the aerodynamic shape design can be done using finite element analysis of fluids, and then a wind tunnel can be used to further modify the aerodynamic model?"
"Correct..." Zhou Yan smiled and nodded, "After a while, the airline's aerodynamic design will be connected to the newly upgraded atmospheric simulation server, and some interfaces will be reserved for you.
At that time, the aerodynamic shape design can be put into the atmospheric simulator, and the wind tunnel is only responsible for aerodynamic shape verification..."
After years of exploration, Zhou Yan has made substantial gains in exploring the "virtual space" of the system. In addition to the published refined solutions to the N-S equations, there are also more modern manifestations: some of the "Dinghaizhu" simulation system
The rendering engine can finally be upgraded...
"By the way, Mr. Zhou, we are confident that the sales of the first batch of cars can start to warm up. It's just a publicity plan..."
"The first way is, of course, to attend a car show, which you are familiar with.
Second, we set up a taxi company ourselves, using all our own cars. The price can be a little higher than that of regular taxi companies. We accept reservations..." Zhou Yan paused, "As for the driver and service, let's highlight the quality a little bit.
…”
"This is a good idea..." Chu Xinyang smiled.
"There is another way..." Zhou Yan glanced at the computer screen, "When we did the 100,000-kilometer test, didn't we have a camera crew following the entire process? After we came back, we found someone to make a documentary and put it on all major platforms...
"
Chu Xinyang nodded: "When promoting, we can spend a little money. Our car is the same as Jeep..."
After confirming the pre-sale plan, Chu Xinyang was about to leave when he was stopped by Zhou Yan: "Also, I will give you a new design project, Niutou Alpha, turtle shell and similar commercial vehicles. After evaluation, the market potential is not great.
If so, I will support you personally..."
"OK!"
After getting off work in Qingyan, Zhou Yan had to rush to Xinghan to pick up his wife. When he left Xinghan Industrial Park, his cell phone rang in his pocket.
"Daughter-in-law, please pick it up!"
Qin Ruoshu took out her cell phone from Zhou Yan's pocket and took a look. The caller ID showed "Feng Jun": "It's Feng Jun!"
"Borrow it!"
"Hey, brother, it's me, Zhou Yan is driving..."
"Oh, okay...Okay, we will do it tomorrow!"
"Oh, bye!"
After hanging up the phone, Qin Ruoshu looked back helplessly and stared at Zhou Yan: "Husband, my second uncle's family came to the capital to discuss the marriage with Xu Wenjing's parents. Tonight's train will go to the Capital Railway Station tomorrow morning..."
Zhou Yan was delighted: "Comrade Lao Feng is also anxious..."
"Husband..." Qin Ruoshu suddenly remembered something, blushed and whispered, "How about we have a child first?"
"I'll go..." Zhou Yan looked at his wife as if she'd seen a ghost, "You'll be pregnant in ten months and you'll be in confinement for half a year. You, a graduate student, will be useless. We're not very old. We'll be completely gone after one and a half years."
question……"
"Oh..." Qin Ruoshu's expression relaxed.
"And..." Zhou Yan thought for a moment, "At the Architectural Design Institute, we are not too busy with work now. Please take two days off. My second uncle is a very pompous person, and we have to support him..."
"Okay!" Qin Ruoshu quickly took out his cell phone and called the head of the department.
In the early morning of the next day, before dawn, Zhou Yan got up and shook Qin Ruoshu, who was still sleeping, awake: "Daughter-in-law, wake up..."
After shaking for a long time, I finally shook the eldest lady awake.
"What are you doing up so early..." As he spoke, Qin Ruoshu suddenly remembered that something really happened today, "I almost forgot..."
"Get up quickly, wash up, and put on makeup..." Zhou Yan looked at the time, "After receiving the person, we have to go to the flag-raising ceremony and have a meal..."
"Look at your future..."
It's five o'clock in the morning in the capital, and the neon lights have not yet fallen. Although there are still stars looming in the sky, many breakfast shops on the roadside are already filled with heat.
The two arrived at the entrance of an alley near Houhai and stopped. A few minutes later, cousin Feng Jun drove out of the alley.
Zhou Yan honked the horn and startled his cousin.
The two cars crossed the First Ring Road, found a large yard near Capital Station, and parked the cars.
After getting off the car, Zhou Yan looked at the time: "There are still ten minutes left, it's still early..."
With that said, he came up to his cousin and said, "Comrade Feng Jun, my second uncle is coming over today. How did you arrange it?"
"After picking up the people, we'll go watch the flag-raising ceremony, and then go have breakfast..." Feng Jun glanced at Zhou Yan, "As for lunch...can you give me some advice?"
"I remember that my third uncle was a soldier in Sichuan. There is a Tianfu Restaurant over there in Sichuan and Shu Building. It has a good reputation. Let's try it at noon?"
Feng Jun nodded: "I remember it's not far from where we live, right?"
After nodding and taking two steps, Zhou Yan quietly looked back at Xu Wenjing, who was chatting with Qin Ruoshu: "Brother, what's going on? Why is it suddenly..."
"Protective measures were not taken well..."
"..."
Zhou Yan was speechless. He was silent for a few seconds before turning his head and looking at his cousin: "Where do you plan to hold the wedding?"
"Go back to Dongyang, your blue sea and blue sky are good..."
