Experimental Investigation and Numerical Computation of Fluid-Structure Interaction on a Square-Section Cylinder with Elastic Surface

Abstract

The work in this paper aims to investigate the effect of elastic wall on flow characteristics using the numerical simulations and experiments, in which the objective is to investigate the influence of the elastic surface on the flow characteristics around a square-section cylinder at Re=1000. As a result, it is obtained that the elastic surface at the back side of square-section cylinder increases the vortex shedding frequency and reduces the fluid forces around it.
