A numerical study is made of the flow past a circular cylinder with/without flow control devices. The Reynolds number ranges from 20 to 200. The numerical method for the solutions of the incompressible Navier-Stokes equations is based on an artificial compressibility approach and an upwind finite-volume method. Two kinds of the flow control devices are. investigated.: (1) placing an attached or a detached splitter plate in the wake behind the circular cylinder. (2) placing a second small cylinder (control cylinder) behind the circular cylinder. The numerical investigations show that. both of two are effective on the suppression of vortex shedding and the reduction of drag.
