Hirst, E

A new integral method is devised to predict the hydrothermal behavior of buoyant jets discharged to infinite, flowing, stratified ambients through single submerged diffusers. The method, based on an integration of the basic partial differential equations written in a natural coordinate system, is more general than previous methods. In addition, a new generalized entrainment function is defined which includes the effects of internal turbulence, buoyancy, jet orientation, and cross fiow. Only one of the 4 entrainment coefficients is obtained by fitting predictions to data. Theoretical predictions are compared with 29 different flows. Agreement between theory and data is good; this is significant as the range in experimental fiow variables is considerable and the 4 entrainment coefficients are maintained constant for all predictions.
