Taking the vertical density-stratified ambient fluid into consideration,a vertical two-dimensional model for buoyant jet was established based on a k-ε turbulent model.Finite volume method and SIMPLE algorithm were used to obtain the solution of the model.Numerical simulation of vertical buoyant jet in linearly density-stratified ambient fluid was simulated,and the distribution of density,trajectory,dilution and width of the jet were obtained.The numerical simulation results were in good agreement with the ...
