Characteristics of Output Power as a Function of Hall Parameter in Capacitive-coupled MHD Generator using Microwave Discharge Plasma

Abstract

A capacitive-coupled magnetohydrodynamic (MHD) generator was demonstrated in a dense working fluid which was generated by a microwave discharge. In this study, the induction voltage from the capacitive-coupled MHD generator was observed in a sinusoidal magnetic field. The observed output voltage of capacitive-coupled MHD generator was not sinusoidal shape waveform in the condition of high Hall parameter conditions. On the other hand, the output voltage of capacitive-coupled MHD generator became the ideal output waveform as lower Hall parameter condition. It suggests that the capacitive-coupled MHD generator also consider the electrode structure for avoiding Hall effect.
