Abstract
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.
