摘要:

This paper focuses on the mixing processes that develop when a jet outfall enters a shallow body of water. With the main purpose of enhancing predictive one-dimensional integral models, a number of non-buoyant and buoyant round jet situations were experimentally investigated with laser Doppler velocimetry and a thermistor system being used to measure velocity and temperature patterns, respectively. Results are presented which show that the dilutions of both non-buoyant and buoyant jets are significantly reduced when the receiving water is shallow. Other mixing features associated with buoyant jets entering shallow water are discussed including; the application of scaling relationships in collapsing integral parameters, possible mathematical relationships which may be used in describing these parameters, the role played by the Coanda effect in influencing the path of the jet and reducing dilution, and, the significance of the differences between the velocity and temperature patterns.
