摘 要：A numercal procedure that applies to both the magnetic diffusion(MHD) and wave propagation regimes of a general plasma/electromagnetic system is presented. The method solves the full Maxwell equations,with or without displacement current, In combination with the Navler-Stokes *** combined system is placed In fully coupled conservation form and embedded in a dual-time formulation that enables classical hyperbolic solution algorithms to be effective across the wave and diffusion limits of the Maxwell *** validity of the algorithm is first established by verifying results obtained with the hyperbolic procedure for the diffusion form of the telegraph equation against analytical *** verification for the electromagnetic equations is obtained by comparing with MHI) simulations obtained from the MACH2 *** numerical calculations are presented for both the wave and MHD limits to illustrate the importance of a solution technique that handles all regimes from Insulators to *** transient operation of a representative,pulsed plasma thruster that contains regions of high density plasma in close proximity with vacuum is presented as a practical application of the method.
