The influences of the Reynolds number and free-stream turbulence intensity on the flow separation behavior around a circular cylinder were investigated experimentally The range of the Reynolds number and turbulence intensity considered are 10,000~45,000 and 0.3~0.6%, respectively Because of ineffectiveness of using time-mean value of hot-film sensor signals in determining the separation location around the cylinder, a new mothod using phase-difference of hot-film sensor signals with hot-wire being located in shedding vortex is suggested The validity of the present mothod is confirmed by the comparison with flow visualization
