Numerical simulation of 2-d model of cooling water draining into the bay with waves and tidal currents

摘要

With the development of economy in coastal zones in China, the energy requirement isincreasing greatly. Many large power plants have been built near bays in China recently, andfunction of power plant need drain large warm water into bays, which will change current fieldnear outfall and have effect on seawater temperature going up in the bay. In this study, thecombined actions of waves and tidal currents in estuarine and coastal areas are considered and a2-d hydrodynamics and temperature transport model by waves and tidal currents has beenestablishedonin which .The wind action and the effect of radiation stress of waves on current andtemperature transport are taken into account. It can simulate the distribution condition in currentfield and temperature field of cooling water correctly and provide credible technical data for oceanenvironmental impact assessment.
