Automotive Fluid−Structure Interaction (FSI): Concepts, Solutions and Applications

From 2012 Automotive Simulation World Congress: Today’s engineering challenges require CAE tools that can solve complex and coupled ultiphysics problems in an efficient manner. In FSI, the complex, coupled response of fluid flow and structural deformation are solved. Advances in coupled solution technology and hardware technology allow multiphysics problems to be solved as an integral part of the engineering design process, instead of simplifying or ignoring the coupled effects. This session presents the technical background and approaches to solve different classes of FSI problems (one-way, two-way, rigid body). These FSI approaches are illustrated through several automotive examples, focusing on powertrain applications.
