a Numerical Scheme for Predicting Transient Shock, Boundary Layer and Magnetohydrodynamic Phenomena.
A stable procedure of first order accuracy for solving the coupled axisymmetric transient gasdynamic and electromagnetic equations is presented. A numerical integration technique for inviscid flow was extended to include viscous and electromagnetic terms with stability, convergence and computational speed comparing favorably with other existing hydrocodes. The method was applied to a number of transient hydrodynamic and magnetohydrodynamic applications characterized by the interaction of gasdynamic, electromagnetic and viscous flow phenomena. The external flow field around an M-117 warhead, an ablating re-entry vehicle and a semi-infinite circular cylinder, and the internal flow of a nozzle, shock tube and MHD channel is examined under viscous and inviscid conditions. Attention focused on the behavior of a conducting fluid in the presence of shocks, boundary layers, heat transfer and electromagnetic fields.
