Wave Disk Generator- Efficient Engine
A Wave disk generator or wave disk engine, as it is called otherwise, is an engine that will revolutionize the automobile efficiency at much lower vehicle costs. It is mainly being developed for use as hybrid vehicle engines. Here’s more info about it.
The concept of this wave disk engine was proposed and demonstrated in March, 2011 and it was called the Radial Internal Combustion Wave Rotor.
What is a Wave Disk Generator?
A wave disk generator is a kind of pistonless rotary power-plant that is being designed at Warsaw Institute of Technology and Michigan State University.
The first kind of wave rotor was designed in the 1950s, which made use of shock waves to transmit energy signals from a high energy fluid to low energy fluid. This inturn increased the pressure and temperature of the low energy fluid. Continuous developments in the field have led to the concept of wave disk generator what we know today.
How does it Work?
This pistonless rotary engine comes with a spinning disk with arched blades. As soon as the fuel and air mixture enters the power-plant, shockwaves are created due to the rotation of disk, which helps in compressing the mixture. As soon as the ignition takes place, the burning combination of air and fuel expands by pushing across the blades, which inturn rotates them. This spinning action leads to the opening and closing of intake as well as exhaust ports.
Similar to all the other heat engines, a wave disk engine’s efficiency is also ruled by the difference in temperature between the cold and hot sides. In contrary to a typical piston engine, the wave disk generator works at much higher temperatures, thus making it more efficient theoretically. The new design is expected to work without a cooling system, thus reducing the overall weight. When you compare it to a turbine based system, it works at a lower rotational speed, thus creating lower stress on the materials.
The very first wave rotor implementations were axial flow, wherein the scavenging process was very complex. On the other hand, a wave disk engine uses a circumferential and radial flow. The curved tunnels give a greater length for the same diameter of disc when compared to the straight tunnels; this allows for proper tuning of travel time for waves.
The Present Status
The wave disk generator is regarded to be an efficient engine with its potential to achieve improved energy efficiency when compared to the typical engines; it can also reduce weight considerably. The most probable application as of now is its ability to charge batteries in hybrid automobiles, which can reduce around 1000 pounds of weight.
