Abstract: The discharge in form of a round buoyant jet into a non-turbulent stratified crossflow may contain five asymptotic regimes in which self-similar flow conditions exist: (i) pure jet, (ii) pure plume, (iii) pure wake, (iv) advected line puff, and (v) advected line thermal. When formulating jet integral models for buoyant jet predictions it is a necessary condition that the model agrees with the five self-similar regimes. It is demonstrated that the buoyant jet model CORJET that forms part of the CORMIX expert system for mixing zone analyses indeed satisfies this requirement when compared to recent good quality data for these regimes.
