摘要
Abstract
Water temperature is increased by a large amount of warm water discharge,and therefore resulting in thermal pollution.A 2-D numerical model was used to simulate an idealized water area.Based on the model,the impact of hydrodynamic condition on warm water diffusion scope was studied,and the effect of water depth and flow intensity where coastal power plant outfall located on warming area was investigated.Results show that with increasing water velocity,the temperature increase is easier to diffuse,which means the area of temperature increase of 4 ℃ is smaller.However,for the 4 m water depth,the area of temperature increase of 1 ℃ increases with increasing velocity.For the 6 m,8 m,and 10 m water depth,the area of temperature increase of 1 ℃ decreases with increasing velocity.For the same boundary condition,the temperature increase area decreases with increasing water depth.Furthermore,for a higher temperature contour,the decreasing rate of temperature increase area is larger.The water depth and velocity have a significant effect on the maximum temperature contour.关键词
