The behavior of heated water jets discharging into a shallow, co-flowing environment was studied in a model which simulated the flow of cooling water from a prototype multiport diffuser discharging into a river or ocean current. The relative effects of jet interaction and surface distortion were considered. The port spacing distance was the most significant variable. Criteria for differentiating among well-mixed flows, moderately well-mixed flows and stratified flows were determined together with the relationship between mixing and distance. A procedure for designing multiport diffuser installations is suggested. (Modified author abstract)
