    This study employs particle image velocimetry (PIV)13; on a jet with and without subjection to internal heating.13; The effects of buoyancy enhancement on the13; entrainment coefficient and on the streamline structures13; responsible for it are investigated. PIV results13; for the unheated jet are in good agreement with earlier13; studies. It is shown that when internal heating is13; present in the flow, the mean entrainment coefficient13; decreases from a value of 0.057 characterizing a standard13; jet to 0.017, at a heating rate of 1400 W corresponding13; to a Richardson number of 0.24. It is also13; shown that the mingling of the entrained fluid with13; the main flow is different in heated and unheated jets.
