Influence of limiters on numerical simulation of heating distributions for hypersonic bodies

The Roe's flux difference splitting (FDS) scheme was combined with min mod, van Leer and Osher-C limiters to simulate hypersonic flow fields around hypersonic bodies. The different effects of the three limiters on the simulation results of hypersonic bodies' aerodynamics and aerothermodynamics were researched, and their effects on the simulation of heating rates were compared and analyzed. From the results, it can draw the following conclusions: the choice of limiters has a very important effect on numerical simulation results, and it will influence the simulation results of aerothermodynamics more than the ones of aerodynamics. The min mod limiter, working together with Roe's FDS scheme can obtain better heating rates on hypersonic bodies than the other two limiters no matter for simple or complex aerodynamic shapes. Therefore, the min mod limiter can provide reliable results for the thermal protection designs.
