【Abstract】 To predict the flow and electric field inside the MHD channel and to gain a thorough understanding of the performance inside the propulsion system, a two-dimensional mathematical model for a direct current, linear channel MHD propulsion system is presented in this paper. By FEM method, the flow and current distributions at the MHD drive section are analyzed, and propulsive force is gained. By comparing with the data of experiment, the correctness of the computation program is validated.更多还原
