High order accurate methods in numerical simulation of hypersonic heat transfer

  • 摘要: 通过高超声速下钝锥热流的计算,对影响热流计算精度的因素进行了综合研究.获得了壁面法向网格Re数对热流计算的影响规律.采用边界高阶插值,提高了热流计算精度.用Roe和AUSM(Advection Upstream Splitting Method)+格式搭配minmod和混合limiter两种限制器,探讨了空间离散方法及限制器的耗散性对热流结果的影响.应用五阶WENO(Weighted Essentially Non-Oscillatory)方法,对高阶格式计算热流的性能进行了细致研究,最终确立了网格依赖小,热流精度高的计算方法.研究认为:高阶格式不但可以放宽热流计算对网格Re数的限制,同时使得格式对本身计算方法的依赖性也变小.
