A finite difference calculation method is used to solve the conservation equations of mass, momentum, and energy in differential form for a buoyant turbulent forced plume discharging vertically into both a uniform and a stratified quiescent ambient. This flow configuration is of interest relative to the discharge of thermal or sewage effluents into the ocean and the discharge of effluents from chimneys and cooling towers into a still atmosphere. The effects buoyancy on the turbulent transport model are discussed. The predictions, including the predicted maximum height of rise for the stratified ambient case, are compared with available experimental data and the results of other prediction methods.
