The two-dimensional turbulent buoyant jet is analyzed using a vertical length scale defined by L = M oFr;1J3 where M o is the rate at which momentum is added at the source and F o is the rate at which buoyancy is added. Introduction of the length scales into the equations of motion shows the ratio x] L directly controls the bouyancy term, The pure momentum jet corresponds to the limit x/L-O and the pure buoyant plume to x/L ..... cc, Utilizing an eddy viscosity model, a similarity solution is presented for the buoyant plume, a series solution is used to develop this eddy viscosity model, and a numerical solution is presented for the buoyant jet. Comparisons are made with available experimental data.
