Research paper on mhd power generation. 15 Numerical Calculation of the Output Power of a MHD Generator INCAS BULLETIN, Volume 6, Issue 4/ 2014 is the magnetic Reynolds’ number, V is the electrical conductivity and P is the magnetic permeability. The MHD generation or, also known as magneto hydrodynamic power generation is a direct energy conversion system which converts the heat energy directly into electrical energy, without any intermediate mechanical energy conversion, as opposed to the case in all other power generating plants.
