A buoyant surface jet in a strong cross-flow (SR 68)

This report deals with an investigation of the near-field behaviour of a buoyant rectangular surface jet discharging normally onto a strong cross-flow. A great deal of work, both experimentally and theoretically, has been undertaken to understand and to model surface buoyant jets in stagnant water, allowing reasonably good predictions of the spread and dilution of wastes. These predictions are inaccurate when the ambient cross-flow is strong. With this in mind a physical model study of a buoyant rectangular surface jet discharging onto a strong cross-flow has been conducted, with a ratio of the buoyant jet velocity to that of the cross-flow in the order of unity.
