Abstract:

Two closely related problems are investigated round turbulent nonbuoyant jets in cross-streams, and inclined turbulent buoyant jets in quiescent homogeneous fluids. Experiments were conducted for the first problem at a jet Reynolds number of 200,000. Pressure distributions on the jet-exit plane, and velocity distributions in the center plane were measured for values. Data on drag forces, jet centerlines, half-widths, and centerline velocities were obtained from the experiments. An integral-type analysis was carried out for the two problems investigated. The equations are solved in Cartesian coordinates for the near-field of both problems and for the far-field of the nonbuoyant jet, and in a natural coordinate system for the curvilinear zone of the nonbuoyant jet.
