摘要: 研究了新型上风格式AUSM+的分辨率、效率等性能,并用它与Roe、vanLeer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。

关键词: AUSM+, 上风格式, 激波反射, 限制器

Abstract: Through comparing different results of simulating shock reflection flow over a forward step using different schemes including Roe and van Leer schemes,the advanced upwind scheme (AUSM+) is fully studied in terms of its resolution and efficiency for shock waves,expansion vaves,contact discontinuities and their interactions.Its advantages of low numerical dissipation and high resolution for discontinuities are demonstrated.

Key words: AUSM+, upwind scheme, shock reflection, limiter
