• The potential distribution in a duct has been measured in the presence of an externally applied voltage. The gas flowing through the duct has been a propane-oxygen combustion gas seeded with K_2CO_3 powder. The voltage-current characteristics has also been measured. The voltage drop is found to increase with the current density but to become independent of it above a critical current density. This critical current density and the voltage drop become smaller as the electrode temperature increases. It is concluded that the main causes of the voltage drop are the thin, cold gas layer near the electrode in the smaller current density region, and the arc column in the region above the critical. Also, it is suggested that the electrode materials in the MHD generator should be selected on the basis of its capability of enduring as high temperature as possible rather than of its low work function.
