摘要:

建立了顺流式、逆流式闭式冷却塔热质交换的数学模型,采用四阶Runge-Kutta方法进行了数值计算,并将计算结果与实验值进行了对比。模拟并分析了两种不同运行方式下闭式冷却塔内冷却水温度、喷淋水温度以及空气比焓的分布。

Abstract:

Sets up a heat and mass transfer mathematical model for both parallel and counter flow type closed cooling towers. Calculates the model by fourth order Runge-Kutta numerical method and compares the results with those from experiment. Simulates and analyses the distributions of cooling water temperature, spray water temperature and air enthalpy.
