A Grid-Free Method for High Reynolds Number Flow Around an Immersed Elastic Structure

Abstract

Finite difference schemes do not perform well in simulations of high Reynolds number flow because a restrictive number of grid points must be used to resolve boundary layers. In this report we present a grid-free numerical method which may be used to calculate flows around an immersed elastic structure. Numerical results are presented in two simple cases: flow past a circular cylinder and flow past a flat past a flat plate. Here the boundary motion is specified and is not time dependent. However, this algorithm can be used to simulate more complicated, time dependent problems in biological fluid mechanics.
