Abstract: Large eddy simulations of turbulent flow around wavy cylinders are performed at Re = 3000. The mean pressure distribution and mean streamwise velocity in the near-wake region are calculated and compared with those of a circular cylinder. The three-dimensional near-wake structures behind wavy cylinders were captured. It was found that due to the long vortex formation length resulting from the three-dimensional vortex sheet of the wavy cylinder, the mean drag coefficients of the wavy cylinders are less than that of a corresponding circular cylinder. A reduction of mean drag coefficient of up to 16% is obtained. Also, the fluctuating lift coefficients of the wavy cylinders are weakened significantly.
