Abstract

Highly separated flows create unique engineering problems and difficult numerical-simulation challenges. The increased availability of high-performance computing systems has renewed interest in accurately computing unsteady flow about relatively simple geometries. This paper investigates flows over a circular cylinder using Cobalt, a finite-volume program, and compare solutions to experimental measurements and other computational work.
