NUMERICAL-SIMULATION OF VERTICAL FORCED PLUME IN A CROSS-FLOW OF STABLY STRATIFIED FLUID

In this study, an investigation using a three-dimensional numerical mo del, which treats conservation of mass, momentum, and salinity simulta neously, was carried out to study the character of a vertical forced p lume in a uniform cross-stream of stably linear stratified environment . A k-epsilon turbulence model was used to simulate the turbulent phen omena and close the solving problem. The performance of the three-dime nsional model is evaluated by comparison of the numerical results with some available experimental measurements. Results indicate that the n umerical computation simulates satisfactorily the plume behavior in a stratified crossflow. The secondary vortex pairs in the cross section induced by the primary one change as the plume flows downstream. This denotes the transformation of entrainment mechanism in stratified cros sflow.
