Fluid-Structure Interaction in the Framework of Numerical Dynamic Simulation of Multibody Systems

In this paper the problem of fluid-structure interaction of solid with kinematically constrained large “ rigid body motion” in fluid flow will be addressed. A spatial coupling algorithm that transfer the displacements from the elastic solid to the flow and the pressure loads from the fluid to solid surface will be based on Radial Basis Function interpolation with a compact support. The difference between conservative and consistent approach, while solving fluid-solid interaction with solid large overall motion, will be tested. Incompressible fluid is modeled by Navier - Stokes equations and solved in OpenFOAM toolbox. Multibody system kinematical constraints will be treated via constraint manifold projection method.
