Numerical investigation and optimization on thermal discharge interactions between drainage heads using three-dimensional CFD method
摘要
Abstract
The impact of power plants' thermal discharge on the environment and aquatic life is significant,making the study of thermal discharge diffusion critical for determining the design parameters of power plants.Three-dimensional CFD simulations were carried out to study the local flow features of the thermal discharge of drainage heads.The effects of different drainage head diameters,heights,and spacings on the interaction of thermal discharge were investigated.It was found that a larger drainage head diameter and height and a lower drainage velocity undermine the interactions of thermal discharge,leading to simpler flow structures.When the drainage velocity is high,the lateral high-speed jet flow causes strong streamwise vortices,resulting in a high-temperature region near the seabed downstream of the drainage heads,which is unfavorable for the fast diffusion of thermal discharge.The area of the 4℃temperature-raise region decreases with the increasing drainage head height.The optimization of drainage head parameters should follow the principles of large head diameter,large head height,and low drainage velocity.On this basis,the spacing between drainage heads can be appropriately reduced.关键词
