Abstract

A jet issuing in cross flow is encountered in several engineering applications. The description of the jet structure and the identification of the sources of the jet wake vorticity, however, are still open questions. This work is part of a series of experimental studies on turbulent buoyant jets in cross flow [1,2]; here, a coherent contribution to the turbulent entrainment and mixing of a buoyant air jet issuing in a cross wind is reported. Further, this work offers support to a theory on the generation of the jet wake vorticity.
