A direct numerical simulation (DNS) has been performed of turbulent channel flow over a three-dimensional Cartesian grid of 30×20×9 cubes in, respectively, the streamwise, spanwise, and wall-normal direction. The grid of cubes mimics a permeable wall with a porosity of 0.875. The flow field is resolved with 600×400×400 mesh points. To enforce...

The Immersed Boundary Method (IBM) is a powerful method for simulating flows in complex geometries [1,2]. In this method complex geometries are embedded on a computational grid, which usually does not conform to the shape of the geometries. No boundary conditions are specified, but instead in the vicinity of solid boundaries forces are imposed...
