Abstract

The present study is to investigate the mechanism of turbulent fluctuation between regular progressive wave and non-buoyant and buoyant jet experimentally. A particle image velocimetry (PIV) technique was employed to measure the instantaneous velocity field and provide quantitative results about mean and turbulent properties via phase-averaged method of all instantaneous velocity maps located at that spatial location. Two kinds of initial effluent were used to examine the effects of buoyancy on the interactions of a turbulent jet under water waves. The experimental results demonstrate that the diffusion of salt water jet changes to a wider profile caused by the wave oscillatory motion. As expected, the width of turbulence intensity of salt water jet increased when it under waves. Furthermore, this confirmed that width and magnitude of the mean flow and turbulence intensity were significantly increased and shifted when the salt water jet was under the wave environments.
