对二维凸台跨声速绕流进行了大涡模拟，研究了激波与湍流边界层的相互作用。网格细化和畴宽的影响进行了研究。特别注意确保物理上正确的入口边界条件。冲击波湍流边界层相互作用引起边界层的强烈分离和事件，如突发事件在传入的边界层，并创建大的流动规模的结构后面的冲击被检测到。然而，虽然根据几个消息来源，这种运动的先决条件已经满足，但激波并没有大规模的运动。
Large eddy simulation was made of transonic flow over a two-dimensional bump where shock wave turbulent boundary layer interaction takes place. Grid refinement and the effect of the domain width were investigated. Special care was taken to ensure physically correct inlet boundary conditions. The shock wave turbulent boundary layer interaction induces strong separation of the boundary layer and events such as bursting events in the incoming boundary layer, and creation of large flow scale structures behind the shock are detected. However, the shock features no large scale movement even though, according to several sources, the prerequisites for such movement are fulfilled.
