Abstract:

Based on the results of an experimental study of a supersonic, non-equilibrium MHD generator, a theoretical optimization of such a generator was performed. It was found that neon seeded with less than 0.1 cesium was the optimum generator working fluid. The maximum generator power output and efficiency was obtained in a constant current density generator operating with a favorable pressure gradient. The optimum channel geometry had an exit to entrance area ratio of about six, linearly diverging channel walls, and a length to average diameter ratio of about ten. It was also shown that a constant velocity generator with a linearly diverging channel geometry had a very low generator conversion efficiency. Author
