摘　　要：针对目前核电机组采用的巨型冷却塔无实际工程应用的现状,采用Fluent软件建立其三维热力计算模型,研究侧风下巨型冷却塔在不同进风口高度下的冷却效果,分析冷却数等热力性能参数,考察了侧风对塔内流场对称性的影响。以提高供电量为最终目标,综合考虑侧风的影响,确定巨型塔最优的进风口高度值。Based on Fluent,three-dimensional numerical simulation model was established to analysis the effective of heat transfer of huge wet cooling towers in nuclear power plant. The essay focused on the tower with different height of inlet under crosswind and analysis the Merkel Number,and the asymmetry leaded by crosswind. Finally it concluded the best height of inlet to supply the most electric power under crosswind.
