  • The behavior of a plane buoyant jet within the zone of flow establishment(ZFE) which is discharged vertically upward into a stagnant uniform environment, is analyzed by the integral equations of mass, momentum and tracer conservation. The analysis includes the spreading ratio with Froude number and geometry of the potential core of ZFE and the length of ZFE. The central velocity at the end of ZFE is found to be influenced significantly by buoyancy, especially at low discharge Froude number. The results provide the necessary initial conditions for the investigation of the zone of established flow.
