| Popis: | Large Eddy Simulations (LES) of complex turbomachinery applications require specific numerical and computational techniques to handle both rotating and static geometries. For finite volume solvers, several different algorithms have been proposed such as chimaera grids and sliding mesh interface methods. The latter method is studied here in combination with an ALE method to treat the moving regions with the Navier–Stokes equations. Due to the relative movement of the grids along the sliding interfaces, the sliding mesh computational method needs to manage non-conformal flux computations and time-dependent processor connectivity, leading to unavoidable modifications of the performance and accuracy of the existing numerical methods. |
