摘要
针对Ｙｅｅ的二阶对称ＴＶＤ格式，利用一开关参数将其和中心差分格式结合构成了一混合格式，讨论了在不同网格下格式粘性的影响，并模拟了简化的超音速进气道流场。
A bybird scheme combined Yee’s second-order symmetric TVD scheme with sec-ond-order certral differencing scheme is given. By this hybird scheme the numerical errorcaused by the dissipative nature of the TVD scheme is studied for different meshs. Thismethod is applied to compute a supersonic flow involving a shock reflection and a shock-boundary layer interaction.The influence of scheme dissipative chameteristics is discussed.
