Model Studies of Outfall Systems for Desalination Plants. Part III. Numerical Simulation and Design Considerations.

摘要

Although at coastal locations,the saline dense effluent from a desalting plant is potentially harmful to the marine organisms,the environmental effects can be minimized or eliminated if the effluent is properly fixed with and diluted by the receiving water. The data obtained in the flume study were used to calibrate several existing models for the jet regime. The model chosen gives a reasonable simulation of the geometry of the jet axis and the dilution at the peak of the jet,but was found to oversimulate the lateral spreading factor. Application of equations to the design of diffusers is presented. Numerical simulation of the dispersion of a dense effluent discharge into a homogeneous stream is included. (Author)
