Applications of Plasma :
Plasma has found many applications, some of them are :
1 Magneto hydro dynamic generates
2) Plasma torch
3) Plasma sprayer
Magneto hydro dyanamic generates :
It consists of combustion gases and this is passed through a special nozzle of a special design called laval nozzle. The density, temperature and pressure decreases continuously. The internal energy also decreases but the kinetic energy of the gas increases continuously such that it surpasses the velocity of sound. Apply a magneto field perpandicular to the nozzle. The field applies a force F on the ions. The positive ions are collected by the electrode m and the negative ions are collected by the electrode. If the electrodes are connected to an external load the current will flow through the load.
The electrical efficiency = power consumed / total power
= I^2 R / I^2R+I^2r
= R/R+r
R = load resistance
r = unit resistance
The internal resistance can be reduced by increasing the electrical conductivity of the plasma. This can be done by adding an alkali metal such as potassium, the thermal effeciency of the generator can be increased by increasing the temperature to 2000k. The e.m.f can be increased by keeping the generator in a powerful electro magnet.
Plasma torch :
A copper tube and a tungsten rod are kept along the axis of the tube. The tube is tappered to form a nozzle. The copper tube is maintained at a high positive potential with respect to the rod............Read
