Abstract
Jet flow, issued into a density-stratified fluid in a tank, and the resultant mixing phenomena are simulated. The velocity and concentration fields were experimentally investigated by the authors' previous study. The upper and lower fluids are water and NaCl-water solution respectively, and the lower fluid is issued vertically upward from a nozzle at the bottom of the tank. The simulation highlights that the jet behavior depends on the Reynolds number and that it agrees well with the experimental result. The simulation also demonstrates that the mixing between two fluids, promoted with the vortical flow induced by the jet, is successfully grasped.
