Development of a steady/unsteady coupled heat transfer solver based on RK/Implicit smoother

摘要

In this work we present a development of a conjugate fluid-heat transfer solver based on a dual-time stepping approach for time dependent problems. We use a finite volume discretization with a RK/implicit smoother scheme for the explicit pseudo-time in the fluid domain and an ADI scheme for the solid domain. The new time dependent scheme is validated with Sod's tube problem. Next, the solution of cooled convergent-divergent nozzle is solved. This case represents a complex physical problem of heating of a solid rocket motor nozzle. The steady state case is compared with experimental results [11]. We also investigate the fully time dependent case.
