Abstract
The object of this work is the modelling and the analysis of fluid–wall interactions in a cylindrical cavity with a unique orifice serving both as inflow and outflow of an incompressible fluid. The analysis shows that the system's behavior is governed by the values of five dimensionless characteristic parameters. The coupled equations system is then approximated by using a staggered scheme which enables to integrate the structure and the fluid parts separately during each time step. A numerical solution is given with the respective influence of each introduced parameter. We conclude by giving an approximation of the viscous friction effects allowing to uncouple the system of equations.
