Abstract
The mixing phenomena of a density stratified fluid by a jet flow in a tank are experimentally investigated.The jet issues vertically upward from a circular nozzle mounted at the bottom of the tank into the density stratified fluid composed of water and 2 percent salt water.The jet Reynolds number Re ranges from 420 to 3160.This study classifies the jet behavior into three patterns according to Re and highlights the mixing of the density stratified fluid by the jet at Re=420.
