abstract

Large Eddy Simulations are performed on a turbulent flow past a circular cylinder with control using velocity-vorticity formulation. The effect of two control methods is analyzed considering aerodynamic coefficients. The influence of rotation and suction velocities is studied. The cylinder rotation and the boundary layer suction induce a lift creation and an increase of lift with control magnitude. Lift value also depends strongly on the suction location which has to be in the vicinity of the separation point.
