摘要

本文通过对湿式自然通风冷却塔内部的流动与传热、传质过程的分析，建立了两维的数学模型，从而获得了详细的塔内空气流速、焓值、含湿量和水温的两维分布。数值计算得到的出塔水温值和现场试验的结果符合良好。对若干塔的热力性能计算分析表明，采用本文的数学模型与计算方法所开发的计算程序具有良好的工程应用前景。

Abstract

Abstract Based on the analysis of flow and heat fransfer and mass transfer in cooling tower

a two-dimensional mathematical model is established

with this model detailed two-dimensional distributions of air velocity

enthalpy

moisture and water temperature were obtained. The water temperature of cooling tower obtained by the numerical calculation is fairly agreed with that measured during test in power plant. Thermal performance analysis of a number of towers shows that this mathematic model and its calculation programme are perspective in technical applications.
