Experiments on round vertical turbulent buoyant jet have been performed using tap water as the jet liquid and saltwater solution as the ambient liquid. Measurements were made of the centerline axial velocity and the centerline and radial concentrations. The integral forms of the momentum and tracer equations were integrated on the basis of an assumption concerning a function of the spreading coefficients. The validity of this assumption has been verified by the experimental results and the analysis led to unified analytical expressions concerning the axial velocity and concentration distributions along the jet axis. The present findings are discussed and compared with previously reported works.
