数值模拟了正常激波从二维通道端壁的反射，研究了激波分岔的非定常、粘性相互作用。数值模拟实现了通量校正输运算法的数据并行版本，该算法已耦合到Navier-Stokes方程的粘性输运项。所有数值模拟均在CM‐5连接机上进行。结果表明：分岔区剪切层是不稳定的，大小尺度涡导致了复杂的流型；此外，与剪切层相邻的高速无粘流在该区域发生偏转。结果产生弱激波和膨胀波，在相互作用区后缘形成再附着激波。研究了传热、雷诺数和入射激波强度对粘性相互作用的影响。热量传递到…
The reflection of a normal shock wave from the end wall of a two‐dimensional channel has been numerically simulated to investigate the unsteady, viscous interaction aspects of shock bifurcation. The numerical simulation implements a data‐parallel version of the Flux‐Corrected Transport algorithm that has been coupled to the viscous transport terms of the Navier–Stokes equations. All numerical simulations were performed on the Connection Machine, the CM‐5. The results indicate that the shear layer in the bifurcation zone is unstable, and the large and small scale vortices lead to complex flow patterns. In addition, the high‐speed, essentially inviscid flow, which is adjacent to the shear layer, is deflected over this region. As a result, weak shock and expansions waves are generated and a reattachment shock is formed at the trailing edge of the interaction region. The impact of heat transfer, Reynolds number, and incident shock strength on the viscous interaction is also investigated. Heat transfer to the ...
