Abstract

Numerical study is conducted to investigate the fluid-structure interaction around a static circular cylinder in two and three dimensional simulations. The cylinder with an elastic surface is fixed in uniform flow at Reynolds number 1000. The objective is to investigate the influence of elastic surface on the fluid forces around the cylinder. The continuity equation, Navier-Stokes equations and Poisson equation are solved by Marker and cell method. The elastic wall is treated by a mass-spring-damper force model that is solved with fluid forces referred from the flow simulation. As a result, it is obtained that the elastic surface at the back side of cylinder (Model D) decreases the drag force on the cylinder.
