Analysis of linear mhd power generators

摘要: The finite electrode size effects on the performance of an infinitely long MHD power generation duct are calculated by means conformal mapping. general transformation is deduced and applied in a graphic way. analysis includes variations segmentation degree, Hall parameter gas electrode-insulator length ratio as well influence external circuitry loading. A criterion for minimum generator internal resistance given. same gives conditions occurrence current leakage between adjacent electrodes. It also shown that highest output at prescribed efficiency always obtained when made to flow exactly opposed Curves presented showing power-efficiency relations other properties depending degree cases axial transverse extraction. implications limiting number identical electrodes introduced combined with condition characteristics generators one or few loads can then be determined completely examples given table. such must not necessarily inferior segmented many independent loads.
