Description
Summary:•For high velocity vehicle, flow model is steady, body heat transfer model is unsteady.•Boundary condition convergency depends on the fluid and solid heat conductivity ratio.•In fluid domain Dirichlet BC should be set up and Neumann BC in solid one.•1D and 3D simulations with FEM and FD methods confirm analysis conclusion. The results of investigation of a numerical technique for coupled heat transfer problem solving for an atmospheric supersonic flying vehicle and flow around it are presented. An iterative numerical algorithm and software package are developed for heat transfer simulation in a flying vehicle structure during its motion in the atmosphere. The convergence of variants of the iterative process for solution matching on the surface with ideal thermal contact is studied. The results of the numerical experiment confirm the obtained theoretical estimates.
