基于AUSM改进格式的超声速射流数值模拟
Numerical Simulation of Supersonic Jet Based on the Improved AUSM Scheme
摘要
Abstract
The complicated supersonic j et varying with coming stream conditions were simulated numerically using the improved second-order AUSM schemes,which was developed to solve the conservative axisymmetric Euler equations based on two-dimensional laws.The numerical results show that the improved method can capture the wave structures of supersonic j et flow fields including incident shock,λshock,reflected shock,constant discontinuity.The numerical results are consistent with experimental data,and the numerical results are better than the results computed by the second-order TVD scheme;Neither nonphysical oscillation nor carbuncle phenomenon occurs near the discontinuous point,which indicates that the improved method has high capacity.The improved method offers a new method to study the supersonic flow.关键词
