摘要: TVD格式是目前数值研究以激波为主要特征之一的超声速、高超声速流场的最先进的算法之一。本文用二阶迎风TVD格式,对三种烧蚀外形的轴对称粘性流场和10°钝锥有攻角三维粘性流场进行了数值模拟,得到了高质量的头部脱体激波和与实验结果及直线推进法计算一致的物面压力分布,表明了TVD格式在再入体粘性绕流计算中的独特优势。

Abstract: TVD scheme is one of the most advanced schemes for investigating supersonic and hypersonic complex flows in which shock wave is one of important properties up to date. In present paper, axisymmetric viscous flows about three indented nosetips and hypersonic flow about a blunt-cone body (θ=10°) at angles of attack were simulated with a two-order windward TVD scheme. High quatitive shocks and surface pressure distributions agreed with experiments and results from space-marching method were obtained. It is also demonstrated the unique advantages of present method for computing complex flows over re-entry vehicles.

Key words: flows around blunt body, TVD scheme, numerical simulation shocks
