Simulation of viscous incompressible fluid interact ion with a moving system is carried out by using finite element method and Newmark approach. Parameters including displacement, velocity, and acceleration are presented as a function of time to describe movements of the solid system. The resulting flow fields such as velocity vectors, and pressure variations are displayed for various time steps. The shear stress along channel walls and the pressure coefficient versus time are also shown in this paper. It is observed that motion of the structural element which becomes a moving boundary had an influence on the flow fields significantly. In a steady inlet flow, the structural system can be balanced by the fluid force, steady-state responses for both structural system and fluid are then reached for a sufficiently long time.
