Abstract

Interaction of fluids with structures play an important role in many industrial applications, e.g. in pumps as major components of conveying processes. This paper concerns the numerical analysis of fluid structure interaction in a pump. The considered system consists of a metal housing, a polymer impeller and the fluid. Thus, we deal with several nonlinearities: large strains, nonlinear material behavior and contact. To analyze this pump, Finite Element Method (FEM) and Smoothed Particle Hydrodynamics (SPH) are coupled, both methods are Lagrangian formulations. Numerical results are presented and discussed. The present study is a benchmark for the analysis of fluid structure interaction with highly nonlinear components. The results show that the presented simulation strategy is suitable for the optimization of such kinds of industrial problems.
