Control of Turbulent Flow over a Circular Cylinder Using Tabs
Mathematics, 2023 In this study, we investigate tabs applied to turbulent flow over a circular cylinder for the reductions of the mean drag and lift fluctuations. Tabs are small and thin passive devices attached to the upper and lower surfaces of a circular cylinder near ...
