Numerical Simulation Of Flow Field And Temperature Field In Intake Port Of Thermal Power Plant

In recent years,with the rapid development of China’s economy,demand for electricity is more and more big,in order to solve the contradiction between power supply and demand,in the coastal estuary and its adjacent waters of the large-scale engineering construction is more and more power plants have been put into construction,waste water plant with waste heat discharged into estuarine and coastal waters,through the water to escape.The installed capacity and stand-alone capacity of the thermal power plant are increasing,and the waste heat is increasing.Due to the diffusion velocity of the heat in the water diffusion rate is far less than that in the atmosphere,so the water discharge and its influence on water quality and ecology has attracted the attention of the relevant departments,corresponding to the needs of engineering construction,design optimization,ecological environment evaluation has been subject to attention.The actual project in Suizhong Power Generation Co.Ltd.as the basis,to carry out the "reduce the rise of research on Numerical Simulation of water temperature,this study focuses on the improvement of plant water temperature through the temperature diffusion numerical simulation calculation,reduce the water temperature measures demonstrate,and provide scientific basis for water supply and drainage plan optimization.In this paper,starting from the actual situation of the project,analysis of power plant geographic location and natural conditions,puts forward 9 kinds of lower water temperature program,established mathematical model of tidal flow and temperature diffusion mathematical model and verified the model.First,through the test of tidal numerical model,before and after the change of flow field and calculation of engineering scheme;and then through the temperature diffusion mathematical model test,calculation of the temperature rise and diffusion temperature;finally,this area of natural conditions and model test results,puts forward suggestions to optimize the scheme of warning.The results of this research have important theoretical significance and practical value for improving water intake temperature in Suizhong power plant.
