In order to reveal the intermittent phenomenon of circular wall jet issuing along cylinder over a time and frequency region, the wavelet cross spectrum was used to analyze the experimental velocity signals between two different fluctuating velocity components. From the wavelet cross spectrum analysis, the instantaneous contribution to Reynolds stress may be easily analyzed. The flow structure of the circular wall jet has been clarified using the wavelet cross spectrum method, comparing with that of the plane wall jet.
