Abstract

Resolution of a near-wall boundary layer is one of hot topics in turbulence modeling. It often requires most of computational time. A non-overlapping domain decomposition method has turned out to be very efficient to tackle this problem for engineering applications. The method is much more universal than conventional approaches based on wall functions. In our approach, the interface boundary conditions are of Robin type and obtained via transfer of the boundary conditions from the wall to the interface boundary. In the current chapter, the technique is extended to the time-dependent Navier-Stokes equations. As a result, the interface boundary condition remains to be of Robin type but it becomes nonlocal in time since contains a memory term. Unsteady effects are analyzed in the chapter.
