Temperature measurements in a negatively buoyant round vertical jet issued in a horizontal crossflow

The problem considered here is the vertical discharge of round negatively buoyant jets through a horizontal crossflow. Laboratory experiments are performed in a flume: fresh water is emitted vertically through warm water. Temperature measurements are undertaken along verticals in the jet axis. It is found that the mean temperature values can be plotted as similarity diagrams. Some experimental correlations are deduced for the maximum height of jet rise. Turbulent temperature quantities do not appear obeying to similarity on the ascending part of the jet. Asymmetry is observed for the various profiles. The intermittency zone was also investigated in some cases
