Combination of the immersed boundary method with compact schemes for DNS of flows in complex geometry

Abstract : We present a direct forcing method better suited for the use of compact finite difference schemes in Direct Numerical Simulation.The new forcing creates inside the body an artificial flow preserving the no-slip condition at the surface but reducing the step-like change of the velocity derivatives across the immersed boundary. This modification is shown to improve results both qualitatively and quantitatively for conventional and complex flow geometries.
