Resolving chemically reacting flow using moving mesh method

摘要：

We apply an adaptive mesh redistribution method to numerical simulation of chemically reacting ows. Our method consists of two independent parts: a ow solver and a mesh redistribution algorithm. We adopt a second-order upwind TVD and LU-SGS schemes for solving the Navier- Stokes equations with finite rate chemistry. The adaptive meshes are generated by solving elliptic equations, with the monitor function carefully designed to resolve the shock wave and the combustion front as well as the induction zone between them. Numerical simulations of supersonic ow past an axisymmetric projectile in premixed hydrogen/oxygen mixture are demonstrated. It is shown that the ow structures can be resolved satisfactorily on adaptive meshes.
