摘　　要：采用Fluent软件通过数值模拟手段研究了冷却塔在建筑屋面布置时不同水平净距对冷却塔气流组织的影响,建议冷却塔距建筑墙体的水平距离不小于4m,以减少冷却塔热排风回流风量和返混率,可为相关工程冷却塔设计提供参考。This article uses Fluent software to study the effect of different horizontal clear distances on the airflow organization of cooling towers when arranged on building roofs through numerical simulation.It is recommended that the horizontal distance between the cooling tower and the building wall should not be less than 4m to reduce the hot exhaust return air volume and backmixing rate of the cooling tower,which can provide reference for related engineering cooling tower design.

关 键 词：数值模拟 冷却塔 水平距离 返混率
