Abstract: A submerged heated water jet issuing from a vertical wall into a turbulent flow in a rectangular open channel is investigated experimentally to determine the mean velocity, turbulence intensity, and temperature distributions in the vicinity of the jet entry. Unlike a free jet, the flow near the jet entry is not entirely controlled by its initial conditions. The presence of boundary layers along the channel wall and bottom restricts entrainment and imposes frictional effect on the jet. The objective of this paper is to provide some experimental evidence on the jet behavior for further development of an analytical or numerical model for the turbulent shear flow.
