Abstract

To investigate the angle effects on the initial mixing processes of the buoyant jet under wave action, the flow visualization and concentration measurements based on laser-induced fluorescence are employed in this study. The dilution improvement of the effluent in the co-wave and opposing-wave is mainly caused by the velocity gradient increasing due to the opposite wave flow and the wave tractive mechanisms resulted from the onshore and offshore wave motion. When orthogonally discharged into wave motions, the effluent is increasingly diluted by the formation of wake vortex and trajectory deflection curved by the wave flow. From the quantitative measurement of tracer concentration, the dimensionless dilution rate shows a function linearly increasing with the dimensionless wave parameter whose coefficient in the orthogonal discharge is above 33% higher than the other two cases. For practical design, it suggests that the orientation of the nozzle should be orthogonal to the propagation of principal wave motion.
