摘要
The fishing ports which equipped the pumping system of deep-sea water for the purpose of sanitation control and fish farming of cold water have increased. It considered using a large-scale entrainment process of a buoyant jet for a water quality improvement of the fishing port. We suggested a new hastening method of seawater exchange by discharging the cold water from the bottom layer of the fishing port to the harbor entrance. The jet area formed by the cold-water discharge to the open area turned into stratified region when the distance from the outfall, which is standard by momentum flux and buoyancy flux, got 20-30 times longer, and most of the part of the stratified region vanished when it got 200-400 times longer. Large-scale entrainment process of a buoyant jet was presumed to be what generates 101-102 times as much large-scale sea water exchange compared with outflow discharge.
