This study introduces the field measurement on a single air inlet induced draft cooling tower (SIDCT) under crosswind conditions. A three-dimensional numerical model is developed and validated to collaborate with the field measurement. The primary objective of this study is to evaluate the effect of environmental crosswind (both direction and velocity) on the thermal characteristics of SIDCT, such as air/water ratio, range, approach, Merkel number, heat transfer coefficient, etc. Measurement results demonstrate that as crosswind velocity rises, the ventilation and cooling performance of SIDCT are continuously enhanced under the crosswind directions of α₁ and α₂, while significantly decreased under α₃. As air flows into SIDCT along the depth direction, the air temperature above drift eliminators decreases firstly and then increases, which follows a reverse trend to the distribution pattern of air velocity. With the increasing crosswind velocity, the water temperature drop increases in the rain zone under α₁ and decreases in the fill zone under α₃, while the cooling capacity decreases in the fill zone and increases in the rain zone, regardless of the crosswind direction. The fitted correlations are derived for predicting the performance parameters with respect to crosswind velocity and direction.

本研究介绍了在侧风条件下对单个进气口引风冷却塔（SIDCT）进行的现场测量。开发并验证了三维数值模型，可与现场测量协作。这项研究的主要目的是评估环境侧风（方向和速度）对SIDCT热特性的影响，例如空气/水比，范围，进近，默克尔数，传热系数等。测量结果表明作为侧风速度上升时，通风和SIDCT的冷却性能被连续下的侧风方向增强α ₁和α ₂，而下显著降低α ₃。当空气沿深度方向流入SIDCT时，除水器上方的空气温度先下降然后上升，这遵循与风速分布模式相反的趋势。随着越来越多的侧风速度，在雨中区中的水的温度差的增加下α ₁和下填充区减小α ₃，而冷却能力在雨区的填充区和的增大而减小，而与侧风的方向。推导拟合的相关性以预测关于侧风速度和方向的性能参数。
