Abstract: Sewage discharged through an underground spout into the ocean often contains a certain quantity of suspended solids, which exhibit complex diffusion and sedimentation characteristics near sewage outlet, and with representative transport processes of a sediment-laden jet. This paper therefore systematically reviews the research progress of sewage sediment-laden jet in still water, crossflow, wave and wavy-crossflow environment, and finds that there are significant differences in sediment deposition patterns for sediment-laden jets in different dynamic environments. Methods on how to accurately describe the multiple dynamic coupling processes of wave-current jet interaction and its influence on sediment transport and sedimentation processes have been a difficult task in the study of sewage discharged sediment-laden jets. Therefore, a recommendation for systematically studying the motion law of sediment-laden jet under the joint action of wave and current based on PIV/PLIF solid-phase separation physical experiment, particle tracking two-phase flow numerical model, and Lagrange integral model is proposed. It is intended to provide an important reference for the optimal design of ocean sewage disposal projects.
