Abstract:

The report presents a summary of the progress during the past year on a continuing investigation aimed at determining the operating characteristics of the linear, non-equilibrium MHD generator. The main effort of the past year was concentrated on reducing the electrode losses in the generator by using heated electrodes which protruded into the gas stream. Using an MHD channel, which was specially constructed for this purpose, large scale electrical power was obtained for the first time in cesium seeded, noble gases at gas stagnation temperatures as low as 2000K. Various electrode structures, both hot and cold, were investigated but the electrode design was not as important as the cesium concentration in determining the electrode drops. During the past year, construction of a larger MHD channel and of a considerably more powerful MHD magnet and power supply were nearly completed. Author
