Characteristics of a MHD power generator using a low-melting-point Gallium alloy.

An experimental investigation of a magneto hydrodynamics power generator using a low-melting-point Gallium alloy at high Reynolds numbers is presented in this paper. The power output is found to increase with increasing the flow Reynolds number. By considering the non-uniform distribution of the magnetic field in the test channel, theoretical evaluation gives a more accurate prediction to the experimental data. The present generator demonstrates the maximum power generation efficiency of $$8.3\times 10^{-4}$$ % and the maximum output electric power of 1.5 mW. [ABSTRACT FROM AUTHOR]
