1. Magneto hydrodynamic (MHD) Power Generationby
Y SANTOSH BABU 08D11A0255

2. MHD power generation uses the interaction of an electrically conducting fluid with a magnetic field to convert part of the energy of the fluid directly into electricity
Converts thermal or kinetic energy into electricity

3. Lorentz Force Law: F = QvB Where
F is the force of the acting particle (vector)
V is the velocity of the particle (vector)
Q is the charge of the particle (scalar)
B is the magnetic field (vector)
Lorentz Force Law:
F = QvB

4. Conversion Efficiency
MHD generator alone: 10-20%
Steam plant alone: ≈ 40%
MHD generator coupled with a steam plant: up to 60%

5. ADVANTAGES OF MHD GENERATOR:
The capital costs of the MHD plants are estimated to be competitive with those of coal fired steam power plants.
The closed cycle system produces power, free of pollution.
It can be used most economically as peak load plant.

6. Losses
Heat transfer to walls
Friction
Maintenance of magnetic field

7. MHD + Steam plant

8. Other uses of MHD Technology
The “Yamoto”: a boat built by Mitsubishi powered solely by MHD propulsion
Can travel at up to 15 km/hr

9. CONCLUSION:
The magneto hydro dynamic power generation is one of the examples of a new unique method of generation of electricity. This power resource play a minor role presently and its use on a vast scale is yet to be confirmed as it is in its childhood stage.
