Large-eddy simulation of separated flow over a three-dimensional axisymmetric hill

Large-Eddy Simulation of Turbulent Flow over an Axisymmetric Hill

Large-Eddy Simulation (LES) of high Reynolds number turbulent flow over an axisymmetric hill of height H = 2δ, where δ is the incoming turbulent boundary layer thickness, is presented in this paper. Surface mean pressure, flow visualization and mean velocity profiles are presented and compared with experiments. In general, good agreement is obtained for the surface mean pressure and axial flow ...

Large-eddy simulation of turbulent open-channel flow over three- dimensional dunes

A large-eddy simulation study has been undertaken to investigate the turbulent structure of openchannel flow over three-dimensional (3D) dunes. The governing equations have been discretised using the finite volume method, with the partial cell treatment being implemented in a Cartesian grid form to deal with the 3D dune topography. The numerical model predicted free surface elevations, mean flo...

Wall-modeled large-eddy simulation of a separated flow over the NASA wall-mounted hump

Wall-modeled large-eddy simulation (WMLES) attempts to provide a predictive but affordable framework for LES by modeling the effect of the computationally demanding inner-layer structures on the outer-layer flow. The grids employed in LES are designed to resolve the outer layer only, thereby reducing the computational cost of LES significantly to affordable levels. The saving in the computation...
