    A Discussion of Schatzmann's Integral Plume Model from a Control Volume Viewpoint

    Abstract: Of the numerous integral models that have been developed to describe buoyant plumes in stratified crossflows, Schatzmann's model appears to be the most mathematically rigorous and physically complete. So far, however, a comparative study of the performance of this model with previous simpler integral models has not been reported. To aid such a comparison, a control volume development of Schatzmann's governing equations is presented to parallel his more abstract differential development. Discrepancies between the equation act derived by Schatzmann and that derived from a control volume analysis are reported. The control volume equation act is found to be consistent with the equations published by previous workers, once Schatzmann's suggestion is taken into account that a mean flow convective interaction between the plume and its surroundings be included along with the usual turbulent entrainment interaction. The source of the discrepancies between equation sets is discussed, and a numerical example is presented to illustrate the effect of these differences in the governing equations on plume predictions.
