Near Field Flow Dynamics of Concentrate Discharges and Diffuser Design

摘要: The major physical aspects of near field mixing dense jets resulting from diffuser discharges concentrate are presented. It is proposed that any environmental impacts such will be local rather than regional, so initial processes an essential component effective disposal scheme. Typical international criteria for summarized; these can readily met by well-designed diffusers. features presented, beginning with the simplest case inclined jet into deep stationary water, followed effects shallow water. We then discuss merging multiport and rosette diffusers it shown their dynamic interaction critical lead to significant changes in flow patterns reduction dilution. Design suggested avoid impaired currents on single discussed. small modifications design Some issues difficulties mathematical modeling flows discussed how entrainment models may not adequately represent phenomena including boundary interaction, re-entrainment, density current dynamics, turbulence collapse. Finally, some open research
