Wall modeled large-eddy simulation of shock wave/turbulent boundary layer interaction with separation
The objective of this work is to assess the ability of large-eddy simulations employing an equilibrium wall model to reproduce the flow features present in strong interactions between an oblique shock wave and the turbulent boundary layers of an internal (duct) flow leading to mean flow separation. Such interactions (denoted STBLI) are pertinent, among other applications, to supersonic flight p...
متن کاملLarge-eddy simulation of turbulent flow over an array of wall-mounted cubes submerged in an emulated atmospheric boundary-layer
Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...
متن کاملLarge-eddy Simulation of Boundary Layer Transition on Swept Wings
The large-eddy simulation of the spatial evolution of a stationary cross ow vortex packet in a three-dimensional boundary layer was performed. Although a coarse grid was used (compared to that required by a direct numerical simulation) the essential features of the disturbance evolution, such as the spanwise disturbance spreading and the vortex rollover, were captured accurately. The eddy visco...
متن کاملDNS of unsteady shock boundary layer interaction
A novel numerical scheme has been developed to simulate high speed viscous flows in complex geometries using unstructured grids. A characteristic–filter based shock capturing scheme is applied as a corrector step to a non–dissipative predictor scheme. This algorithm is being used to study shock turbulent boundary layer interactions and this paper presents the results of a turbulent flow at Mach...
