Chapter 1217 We are not joking
Magnetic fluid power generation is not a new term coined by Chang Haonan himself.
In fact, this concept originated quite early and can even be traced back to Michael Faraday, the founder of electrodynamics.
The first patent for magnetic fluid power generation was also granted in the United States in 1910.
Then...
There is no more.
Although the theory is rich, in the following nearly a century, mankind has never been able to master reliable technical means to generate high-speed plasma.
It was not until the beginning of the 21st century that humans built practical magnetic fluid power generation verification equipment for the first time.
Said to be equipment, in fact, due to the strength and speed of the magnetic fluid, the scale and power generation are still very small.
Closer to some kind of toy.
It would be okay if that was all.
After all, mankind has achieved nuclear power generation for the first time, and the power is also not enough to light a light bulb.
The key is that there seems to be no prospect of further breakthroughs in the short term.
In short, even within the industry, it has not caused much trouble.
So after hearing Chang Haonan's answer, Jiang Zonglin did not immediately think about the application.
Instead, he directly began to consider how to weaken this effect:
“So, as long as the magnetic fluid no longer cuts the magnetic field lines, no induced electric potential will be generated?”
What Chang Haonan just said This is exactly what the proposal means:
“That’s right.”
He nodded:
"The equipment's magnetic field and the geomagnetic field are both roughly horizontal to the ground and running east-west, so there will be no problems during normal wind tunnel work... But after adding the gas circulation facility, the flow direction of the magnetic fluid will change. Resulting in the loss of part of the energy..."
"Actually, it is not bad to simply lose energy. I am worried that the gas flow rate you created is too fast and the induced potential difference is too large, which will cause risks to the equipment itself..."
This last sentence is obviously a bit joking.
Not to mention the total airflow temperature of 8000K, even if the airflow temperature really reaches 8000K, it is not enough to completely ionize the working fluid gas mainly composed of nitrogen and oxygen, let alone reach the 10^6S/m volume of solid metal. level of conductivity.
If it were so easy to cause danger, then magnetic fluid power generation technology would not have been ignored for decades.
What's more, the installation method of the wind tunnel itself is strictly grounded. Even if there is a voltage of hundreds or thousands of volts, it will not really damage the equipment itself.
Jiang Zonglin on the other end of the phone could naturally hear it, and immediately smiled heartily and said:
“Don’t worry, Mr. Chang, we will comprehensively check the structural safety of the equipment after every test. , guaranteed to nip all risks in the bud! ”
"Okay, I'll wait for your good news!"
The JF14 wind tunnel is the top priority of the current work of the Mechanics Institute, so Chang Haonan did not talk to Jiang Zonglin anymore. There were many other things to do, and after some routine encouragement, the call ended.
But after putting down the receiver, he immediately took out a notebook from the drawer on the right side of his desk.
The leather cover has shown signs of aging, and the sides of the book have been almost completely dyed black due to frequent flipping.
It is not difficult to see that it has been used for quite some time.
Chang Haonan bought this from a stationery store at Jinghang University shortly after his rebirth.
Used to record some inspirations or ideas that are not yet ready for research and development, but will be useful in the future.
He opened the book and wrote a title on the top of a blank page:
Detonation-driven magnetic fluid to generate electricity——
At least 90% of the difficulty of magnetic fluid to generate electricity is It comes from how to generate high-energy airflow with sufficient speed and conductivity.
The detonation drive technology, which was born out of ultra-high-speed wind tunnels, can exactly meet this requirement.
Of course, it can only produce a moment of no more than 0.01 seconds.
It is a pipe dream to use it in normal power generation equipment.
But what if... it happens to be a pulse power supply?
At present, the most important pulse power supply is a capacitor power supply that stores energy in the form of an electric field.
However, electric field energy storage has extremely high performance requirements for high-power intermediate energy storage components, which often have extremely exaggerated size and cost.
Take the capacitive pulse power supply as an example. If you want to achieve an energy storage of more than 100MJ, then the capacitor alone will reach an astonishing volume of about 100 cubic meters.
And it’s still growing exponentially.
As for mechanical means such as flywheel energy storage and gravity energy storage, the upper limit is too low due to conversion efficiency issues, and they are often more suitable for steady-state power supplies.
Magnetic fluid generators that do not require high-power switches, have no rotating parts, and can directly transfer energy to the load do not have these concerns.
It can be used in situations where it is inconvenient to use capacitor/inductor energy storage... Chang Haonan wrote quickly and quickly filled up a whole page in his notebook.
After stopping to think for a moment, he added four asterisks at the bottom.
Priority four stars.
That is, not to start research and development right now, but to invest resources in it as soon as objective conditions permit...
...
Chang Haonan is working hard on writing here While writing illness.
Hundreds of meters away, the Haofa factory area.
A row of four Coaster minibuses, led by two small cars, rushed in and finally stopped at the entrance of a workshop.
Originally, this was supposed to be a loading and unloading area for raw materials and products. Under normal circumstances, passenger vehicles are not allowed to stay, so as not to affect the operation efficiency or even cause danger.
But today’s situation is obviously not ordinary.
Almost at the same time that the convoy came to a stop, a team of about thirty people also came out of the workshop not far away.
The two people in the middle of the crowd, one is Ren Bingda, deputy general manager of Haofa Group, obviously appearing as representatives of the host.
The other one has a white face and a pass hanging around his neck.
It was none other than Tim Purdy from Rolls-Royce.
To some extent, he and Ren Bingda are old acquaintances.
Today’s visit was specially arranged by the latter.
In fact, Bodi received a request from his immediate superior about six months ago, asking him to contact China regarding the next stage of aviation engine emission standards.
But on the one hand, after the Trent 900 crisis ended, Bodie, or the entire Rolls-Royce company, also returned to its traditional British efficiency.
On the other hand, Bodi had just taken over the Next Generation Medium Thrust Turbofan Engine (NGME) project. As the leader of the team for the first time, he did not even have time to understand many situations, and he did not leave for a while. Not quite open.
So it is not until now, the third quarter of 2005 is almost over, that this trip was finally made.
Fortunately, after China issued that harshly worded draft, it has not made any public statements on the issue of aviation emissions.
It seems to have really verified the previous suspicion that the promotional draft was to coordinate the public opinion offensive against the United States at the IPCC conference.
At least in Bodi's opinion, he shouldn't have delayed anything.
Especially after arriving in Haojing this time, Ren Bingda, who was in charge of the reception, changed his aggressive style when he was in the UK and received him with a very high standard.
We even arranged to visit one of the core production workshops of Haofa Group.
This is the place where turbine blades are processed for the Trent 900.
Although nothing can be seen from this quick glance, and many of the core processes have obviously been temporarily suspended.
But letting him in is itself a gesture of friendship and mutual trust.
In short, Bodi's mentality at this time is quite relaxed.
"Ren, although our cooperation has lasted for several years, this is the first time I have seen your production process with my own eyes. To be honest, it is very unexpected..."
After getting in the car, Bodi gave a rather sincere compliment to the trip.
"Where."
Ren Bingda then sat opposite him and waved his hand modestly:
"Compared with an established company like yours, there is still a lot to learn. ”
This is not entirely polite.
As the level of Haofa Group has continued to improve in recent years, especially after the establishment of the AE1500/Turbofan 20 project, he can increasingly feel that although Huaxia already has many unique skills in the field of aviation engine technology, in the There is still a lot of room for improvement in the accumulation of hard power, especially in the fields of production and management.
Including this meeting with Bodi, it was also in accordance with Chang Haonan's previous arrangements to strive to cooperate with Rolls-Royce to further fill the shortcomings of entering the civil aviation industry.
After some pleasantries, Bodi still couldn't stand it. Ren Bingda kept talking about him and got to the point first:
"Ren, I remember you released a news at the beginning of the year, saying Yes will be in CAEP6 On the basis of emission standards, reduce cruise fuel consumption by 8% and exhaust emissions by 16% to 30%?”
Because he had just judged that China was probably bluffing, so this meeting was just a casual chat. mentioned in a tone of voice.
But after hearing this, Ren Bingda smiled first, and then nodded very solemnly:
"That's right."
