摘要	In this paper, numerical simulation of a hemodynamic fluid-structure interaction (FSI) problem with an immersed rotating structure is carried out. A dynamic FSI problem involving a rotational elastic solid, which is modeled by the incompressible shear stress transport (SST) k-omega turbulence model in the fluid domain and by a co-rotational linearized St. Venant-Kirchhoff model in the structure domain, is studied and applied to a type of artificial heart pump. A monolithic arbitrary Lagrangian-Eulerian mixed finite element method, which is modified to adapt to the interaction between fluid and an immersed rotating structure, is employed to discretize the coupled FSI system. The Newton's linearization and the streamline-upwind/Petrov-Galerkin (SUPG) stabilization are employed to overcome strong nonlinearity and dominant convection effects, respectively. Numerical validations are preformed and compared with a commercial CFD software. This paper is an extension to our recent conference paper [1]. (C) 2018 Elsevier B.V. All rights reserved.
