The measurements of velocity vectors are made in the wake(X/d=8) of a circular cylinder with arc grooves. The experiments are conducted by changing the groove numbers, groove depths, Re numbers and first formed groove angle and we know that the optimum groove angle is 70 degree and the wake velocity profiles are improved at a few conditions. According to vortex shedding frequency distributions, the key solutions to vary the flow field behind the circular cylinder are 70 deg groove angle and more deep grooves.
