Based on the author's former research on thermal response in the thermal protection layer of the leading edge, the numerical simulation of the thermal response coupling with the hypersonic flow that leads to the aerodynamic heating on the surface of the thermal protection layer is performed in this paper. The thermal response is obtained from the unsteady heat conduction equation by introducing arbitrary coordinates-transformation.

Based on the author's former research on thermal response in the thermal protection layer of the leading edge, the numerical simulation of the thermal response coupling with the hypersonic flow that leads to the aerodynamic heating on the surface of the thermal protection layer is performed in this paper. The thermal response is obtained from the unsteady heat conduction equation by introducing arbitrary coordinates-transformation. And the hypersonic flow field is obtained from Navier-Stockes equations by using NND scheme. This coupling numerical simulation is very different from the non-coupling calculation that is commonly used in scientific research and engineering applications, which is of advancing to the calculation about the thermal protection. Also the simulation is used as the basis of both the research of heat transfer enhancement and the full-coupling calculation of the external flow field, thermal response and thermal stress of the thermal protection structure.

To achieve coupling numerical simulation of the whole fields including flow field, electric field, magnetic field and chemical reaction efficiently and to illustrate the characteristic of electromagnetic field within arcjet thruster flow region, an appropriate electromagnetic field model was established and detailed investigation on numerical solution for it was carried out. The electromagnetic field model was based upon the steady-state operating characteristic of the thruster and the control equation was simplified from Maxwell’s equations. Finite control volume integral method was adopted to discretize the elliptic control equation and nine different iteration techniques were introduced to solve the discretized equation numerically. Convergence speed, stability of solution and ultimate precision of each iteration technique are presented. The investigation indicates that Gauss-Seidel successive line over relaxation method is an efficient numerical solution in this instance.
