Comparison of sharp and smoothed interface methods for simulation of particulate flows II: Inertial and added mass effects

This paper studies the robustness of the Smoothed Profile Method (SPM) in fluid-solid interaction problems where inertia and added mass effects are significant. The performance of SPM is compared with that of a Sharp Interface Method (SIM), which is constructed with second-order discretization schemes. The applicability of SPM is extended to the moderate Reynolds numbers regime where the boundary layer and wake dynamics are likely to be influenced by the thickness of the solid-fluid interface. It is shown that SPM is able to correctly predict the drag and surface vorticity forRe
