2003 World Scientific Publishing Co. Pte. Ltd. The behavior of a neutrally buoyant horizontal turbulent round jet under a wavy environment was investigated using the Particle Image Velocimetry (PIV) technique for velocity measurements. The mean and turbulent quantities were extracted using the phase-averaged method for analyses. The mean centerline velocity along the jet axis, the jet half-width, and the jet cross sectional mean velocity profile under different wave amplitudes and at different waves phases were demonstrated and compared. The results suggest that the influence of wave amplitudes on the jet dilution rate is significant while the influence of wave phases on the jet behavior is relatively small.
