N2 - Heat fluxes from a supersonic high temperature inert gas flow to electrodes in a disk MHD generator are measured under the strong influence of Lorents force. When we compare heat fluxes from the inert gas flow to electrodes with and without magnetic field, it has been observed that strong MHD interaction significantly increase heat fluxes especially in the middle region of the disk generator. This increase of heat fluxes shows a strong correlation with rise of the static pressure induced by the MHD interaction. By raising the inlet temperature of the inert gas, the region with strong MHD interaction expands to upstream because of shortening of the ionization relaxation region. For the same static pressure rise, helium shows more significant increase of heat fluxes than argon, which may ascribed to an unstable fluctuated helium plasma.
