Abstract
There is an ever growing industrial demand for the numerical simulation of complex industrial flow problems. Although historically Reynolds-Averaged Navier-Stokes (RANS) methods been have been widely used for such applications, there are many flow cases for which RANS simulations are unsuitable. These include studies of the effects of flow control devices on turbulent boundary layers, as researchers are interested in how such devices interfere with the structure of the turbulence. To solve such flow problems, Large-Eddy Simulations (LES) can be used. In the current study, the focus was put on providing an objective comparison of inflow modeling techniques applicable to the simulation of flow control devices in a coarse LES framework, with a special interest in general techniques applicable to a large range of flows.
