Finite element analysis of fluid motion with an oscillating structural system
Analysis of unsteady flow through an oscillating structural system is carried out by using consistent penalty function finite element method and Newmark approach for both fluid and solid. Physical variables 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 distributions are displayed for various time steps. The shear stress along channel walls and the pressure coefficient versus time are also shown in the paper. The results revealed that motion of the solid body which becomes a moving boundary had a significant influence on the flow fields. In a steady inlet flow, the structural system can be balanced by the fluid force, and steady state responses for both fluid and solid are then reached for a sufficiently long time.
