Abstract

This study reports selected benchmark results of an IBM based finite volume solver within the framework of the open source toolbox foam-extend 3.2. The immersed boundary formulation uses a discrete forcing approach based on a weighted least squares approximation that preserves the sharpness of the boundary. In this context, we present two test cases: (1) a 2D cylinder which oscillates transversely at a flow Reynolds number of 185, and (2) a 3D, rigid plate that pitches about its leading edge at a Reynolds number of 2000. Preliminary force coefficient results are compared with available computational and experimental data. In addition, a snapshot POD analysis was performed on the pitching plate problem to reveal the energetic modes and to identify the large-scale structure of the wakes.
