Physical And Numerical Simulation Of The Heated Discharge In Tidal Area

The fire and nuclear power plants near ocean areas often use seawater as source to cool the equipments, and then discharge it into the sea. This process brings great influences on the intake and surrounding waters. Subject to the tidal effects, the layout of the intake and outlet projects and the impact scope of excess temperature are relatively more complex.In this paper, a specific project is studied, respectively according to numerical and physical simulation. First, the theoretical base for ANSYS simulation calculation is analyzed, including the fundamental principle of the numerical simulation of tidal flow, the characteristics of each numerical calculation method, and the control equation of the tidal flow. Second, a physical model is designed with the specific conditions of the project, according to physical simulation principle and other similar principles. The design involves the model ratio, area, management system and so on. Third, the experiments are taken to validate the physical model. Then the discharge solution is selected when model tidal field is reliable, and the impact scope of excess temperature is predicted. At last, the heated discharge is numerically simulated and calculated by ANSYS, under typical condition. The numerical-simulated results are compared with the physical-simulated results, in order to prove the credibility of researching results.
