研究了新型上风格式AUSM+的分辨率、效率等性能,并用它与Roe、van Leer上风格式数值模拟了前向台阶激波反射流动,通过对激波、膨胀波、接触间断及其间相互干扰的复杂波系的模拟对比,分析探讨了AUSM+格式的低数值耗散、间断高分辨率等特性。(The resolution and efficiency of the new upwind scheme AUSM+ are studied, and the flow of forward step shock wave is simulated with the Roe and van Leer upper wind format. The low numerical dissipation and high discontinuity of the AUSM+ format is analyzed and compared through the simulation and comparison of the shock wave, the expansion wave, the contact discontinuity and the interference of the AUSM+. The characteristics of resolution and so on.)
