摘要
Abstract
Since the advantage of cooling tower with water collectors devices is obvious at high performance,energy conservation and low noise,this type of cooling tower has been widely used in fire and thermal power plant.This paper focuses on tower performance by CFD,while establishing thermal and aerodynamic characteristics of three dimensional numerical model about the tower.The numerical simulation results show that:(1) Although the cooled water-collectors increase flow resistance,but this increment is significantly less than the decrease of resistance of rain zone.(2) The ventilation quantity of the tower with cooled water collectors is larger than that of conventional tower in the same situation.(3) The cooling efficiency of the tower with cooled water collectors is superior to the conventional tower.关键词
