Rising: Ten Thousand Years

Chapter 150: The era of alternating current

Views:

gradually.

The guests who joined the meeting all discovered a phenomenon. After all, no one at the scene was stupid. Everyone realized that this time the Department of Physics of the Kyushu Academy of Sciences seemed to be making big moves.

The results of the Electromagnetic Research Institute are actually interdependent.

One is the development of electric motors, which express the understanding of electricity more thoroughly and straightforwardly. Electricity is also a kind of energy, the same energy as steam energy, an energy with unlimited potential.

Immediately afterwards, the Institute of Electromagnetics launched the alternating current theory.

These two scientific research results are interdependent. The electric motor needs more powerful alternating current to support it, and the power will become extremely large.

The development of alternating current theory is also imminent.

If the two players who came on stage were not worth thinking about, then the results brought by the third one from the Mechanical Power Academy completely made everyone present have a hint of meaning.

"Hello everyone, I am Qin Enze, dean of the Mechanical Power Research Institute of the Department of Physics of the Kyushu Academy of Sciences."

The ugly guy with a face full of hideous scars and a closed left eye walked onto the stage. He looked so handsome in a Chinese tunic suit that people actually ignored his appearance.

Qin Enze glanced at the audience and said calmly: "The research result brought by the Motor Vehicle Institute this time is a steam turbine."

As soon as this statement came out, everyone below was in an uproar.

"Steam turbine? Is it a steam engine?"

"Why is he frying leftover rice? Didn't they already have a steam engine? It's hard to say whether you can win an award with this."

"Steam turbine? What's the difference between it and a steam engine?"

“…”

Qin Enze made a gesture of invitation: "Please move to the square outside, and I will demonstrate the steam turbine live."

Everyone stood up and the staff arranged for evacuation. A thousand guests walked out of the venue with some curiosity and stood outside the warning line drawn with white plaster in advance.

In the field, there were a lot of machines. There are some disassembled parts scattered around, and in the center is a machine with an irregular shape the size of a water tank.

Everyone was a little excited looking at the metallic-colored machine. No matter what era, men can never resist the beauty of machinery.

Li Zhen and Ge Qingping sat on the judges' bench and looked at the machines in the field with smiles.

As a judge and the president of Kyushu Academy of Sciences, Li Zhen naturally knows what achievements each academy has achieved. Ge Qingping also knew something about it. Therefore, Ge Qingping was even more excited. He just read the introduction to steam turbines and knew what effect this big guy would bring to the scientific process in the future.

Qin Enze was very high-spirited at this time and led the members of his hospital to make preparations. He extended his hand and introduced: "As you can see, this is a steam turbine."

"If we talk about the difference between a steam engine and a steam turbine, let me briefly explain it here. A steam engine uses steam as a working medium, uses it to expand in the cylinder to push the piston to do work, and uses the nature of water vapor to easily liquefy to achieve circulation. A steam turbine uses The expansion of steam in the turbine drives the turbine to do work, and its internal structure is similar to that of a turbine. Compared with a steam engine, the efficiency is greatly improved."

"What is a turbine?"

Qin Enze walked to a row of disassembled parts and pointed to the dense row of fan blades: "This is the turbine. It is the fan in the power machine. When the steam passes through the turbine fan, the energy will be obtained in a geometric multiple. The expansion in turn drives the turbine to rotate, and the turbine drives the rotor to rotate. It is a rotary power machine that converts the energy of the flowing working fluid into mechanical work."

"Compared with steam engines, they are machines that can be used for different purposes. A steam engine has a huge torque and generates a large force, but its rotation speed is relatively slow. A steam turbine, on the other hand, rotates at ultra-high speed but has a small torque. Of course, This torque is only relative.”

Qin Enze fixed the blades of a fan on the rotor of the steam turbine with mortise and tenon snaps: "In order to let everyone feel the efficiency and energy of the steam turbine more intuitively, we can observe the performance of the rotor through the fan blades. spinning speed."

Someone lit up the boiler, and the inside of the boiler quickly started boiling under the raging fire. The exhaust gas was discharged from the chimney, and billowing white smoke and black smoke from coal burning rushed into the sky.

Qin Enze snapped his fingers: "It's time to start."

Someone suddenly pulled the air plug, and instantly, a terrifying roar spread throughout the Kyushu Academy of Sciences.

'Woooooo—'

A sharp, fierce roar of steam jets came.

The people who were close quickly took a step back and subconsciously covered their ears. They were shocked in their hearts. Why is it so strong

They all know very well about steam engines, but even steam cars are not that powerful. This steam turbine looks about the same size as a steam engine, but is it too powerful? It was deafening and could be heard by the sound.

Mixed with the whistling sound was a sharp sound breaking through the air.

Suddenly, the fan blades connected to the rotor began to rotate rapidly.

"Ah. So fast!"

"Oh my God, what a speed."

"Isn't this too powerful? When the steam car spins at its fastest speed, it's not even one-tenth as powerful as this."

“…”

Someone stood directly opposite the fan, wanting to feel how fast the wind was.

But as soon as he stood there, he felt waves of flying sand and rocks, and a terrifying storm struck.

'Huhu'

The man exclaimed and found that the coat he was wearing was missing, and he couldn't open his eyes. But he was seven or eight meters away from the fan blades.

Staggering, the man squatted on the ground and quickly crawled to the side, exclaiming: "What a strong wind, what a terrifying energy. It blew me so hard that I couldn't even stand still."

Qin Enze shouted amidst the roar of a large steam turbine: "This is the super power of the steam turbine. Now the boiler is not boiling enough, and half of its potential has not been used."

What!

It can be faster!

The thousand guests were all dumbfounded. This power is too terrifying, right

Qin Enze continued to shout: "Compared with reciprocating steam engines, the steam flow in the steam turbine is continuous and high-speed, and the flow rate that can pass through the unit area is large, so it can emit greater power. High-power steam turbines can use higher The steam pressure and temperature are high, so the thermal efficiency is high. And this high power and low torque can be used in more places."

"Through the ideas of our School of Mechanical Power, we can build large iron-clad battleships. Abandon the current wooden ships around the world and use them on iron-clad ships. The steam turbine drives this fan-shaped propeller to rotate, which can produce terrifying thrust. Realization: The ship is large, heavy, heavy, and has a deep draft. But it is fast, agile, agile, and maneuverable. According to our theoretical assumptions, if steam turbines are installed on existing Kyushu naval battleships, the speed of the ship will be increased by at least ten More than times."

"ten times!"

Lin Ke of the General Military Administration took a breath of air, let out a scream, and his eyes turned green.

Without giving Lin Ke too much time to be surprised, Qin Enze shouted again amidst the roar:

"And we are preparing to join forces with the Institute of Electromagnetics to open Kyushu's first large-scale thermal power station. The use of steam turbines will be used by the Institute of Electromagnetics as the main core of power generation. After theoretical assumptions by colleagues from the Institute of Electromagnetics, a thermal power station unit will be built. The turbine works at full load for 24 hours, generating at least 7 million kilowatt-hours of alternating current. This is equivalent to if the entire Qingdao County is laid with an AC power grid, and the thermal power station generates electricity for one day, according to the current level of electricity usage, it is enough for the entire Qingdao County. Millions of people, use it for seven days!”

After saying this, everyone's hearts skipped a beat.

All the giant merchants from Kyushu present were shaking crazily...
