Control of flow past a dimpled circular cylinder

•Force and flow characteristics of smooth and dimpled cylinders are presented.•Dimpled surface is effective in reducing the mean drag and r.m.s. lift coefficients.•Dimpled surface could reduce the strength of vortex shedding from the cylinder. In this paper, the flow past a circular cylinder with di...
