本文针对具有二次涡复杂分离再附现象的激波边界层干扰流动 ,数值地考察了扩散抛物化Navier Stokes(DPNS)方程组的适用情况。壁面摩阻和压力、主涡和二次涡的涡高和涡长、分离再附位置以及流线图等特性的计算表明 :DPNS方程组的数值结果均与NS方程组的数值结果很好相符
In this paper, the perturbations of shock boundary layer with complex secondary vortex separation and reassimilation are investigated numerically for the application of the diffusion parabolic Navier Stokes (DPNS) equations. The calculation of wall friction and pressure, the vorticity and vortex length of main and secondary vortices, the position of separation and reattachment and the flow chart show that the numerical results of DPNS equations are in good agreement with the numerical results of NS equations
