Abstract

An artificial compressibility method for solving the incompressible Navier-Stokes equations has been applied to the study of flow past a circular cylinder with and without flow control devices. The Reynolds number ranges from 46 to 200. The numerical method is based on upwind finite volume methods for space discretizations and an explicit Runge-Kutta time integration with implicit residual smoothing methods for time discretizations. Two kinds of flow control devices are investigated: (1) placing an attached or a detached splitter plate and (2) placing a second small cylinder (control cylinder) behind a circular cylinder. Numerical investigations show that both are effective in the suppression of vortex shedding and the reduction of drag.
