An adaptive ALE residual based penalization approach for laminar flows with moving bodies

Abstract : The coupling of anisotropic unstructured mesh adaptation techniques with an immersed boundary method (IBM) called penalization is studied for time dependent flow simulations involving moving objects. To extend Residual Distribution (RD) method to the penalized Navier Stokes equations, a new formulation based on a Strang splitting is developed. To reduce the error on solid boundaries, unstructured mesh adaptation based on an elasticity model is used. Keeping a constant connectivity, the mesh evolves in time according to the solid position, and the new formulation is proposed in an ALE framework.
