摘要
本文采用显式 TVD 格式,求解薄层 Navier-Stokes 方程,计算了激波与楔面相互干扰的流场情况,得出了马赫反射的各种等强度线及固壁面上详细的物理量分布,根据计算得出的流场,计算了壁面摩擦阻力及热流分布。
An explicit TVD scheme is used to solve the thin-layerNavier-Stokes equations in the present paper,and the interactive flowfield between a shock wave and a wedge is calculated.A few constantvalue lines and the detailed physical quantity distributions at solid surfaceof Mach reflections are obtained.The skin friction distribution and therate of heat transfer at the solid surface can further be obtained throughthe calculated flow field.
