ANALYSIS OF COUPLED FIELD FOR LINEAR MHD PROPULSOR

摘要

To predict the flow field and electric field inside the magne- tohydrodynamic (MHD) channel and to gain a thorough under- standing of the performance inside the propulsion system, a two- dimensional mathematical model for a direct-current, linear-channel MHD propulsion system is presented. By FEM and FDM method, The flow velocity and electrical current distributions in the MHD Drive section are analyzed, and propulsive force is obtained. Via Comparison with the experimental result, the correctness of the Computation program is validated.
