逆流式冷却塔填料及淋水分布的数值优化设计

Numerical Optimization on Arrangement of the Filling Material and Spraying Water in Cooling Tower

在逆流式自然通风冷却塔流场、温度场和湿度场数值模拟工作的基础上 ,采用数值分析的方法研究了非均匀填料分布及非均匀淋水密度分布对提高冷却效率的影响 ,结合某电厂的工程设计实例 。

The arrangement of the filling material and spraying water is very important to improve the cooling efficiency in a huge cooling tower. In this paper the effect of nonuniform arrangement of filling material and spraying water was investigated based on numerical simulation using a developed software, named NSWCT (Numerical Simulation of Wet Cooling Tower). As a result of numerical optimization a best arrangement of filling material and spraying water will be used in a practice cooling tower design.
