Test results on buoyant jets injected horizontally in a cross flowing stream

Experiments were conducted to study the behavior of axi-symmetric turbulent buoyant jets injected horizontally in a cross flowing current. Experimental work was simulated by injecting a fluid emanating from a. round nozzle into a fluid of lighter density flowing in a wide channel at approximately uniform flow. A salt tracer technique was used for jet dispersion studies. In this study, material concentration profiles were measured across various sections along jets of different parametric values. From these profiles, concentration distribution curves as well as maximum concentration and dilution values and their variation with distance along the jet were determined. Half jet radius values were calculated to study the expansion of the jet. Jet boundaries and trajectories were studied photographically and compared with measured values. The effect of the ambient current on the overall shape of the jet was established by the study of the measured complete concentration section across the jet.
