Abstract

In this paper, the results of an investigation into the internal hydraulics of a long sea outfall are presented. The investigation focuses on the mixing and stratification of the saline receiving water and the discharged wastewater within the outfall difruser. The research methods include a combination of numerical modelling and laboratory testing. The paper provides details of an enhanced numerical model of outfall operation. The model is designed to reproduce the internal hydraulics of the outfall including buoyancy and stratification, so that the interaction between the saline sea water and the effluent may be predicted. The numerical model has been developed using the FLUENT/UNS computational fluid dynamics (CFD) package. Mixing
