立式喷淋室内气-水逆流热湿交换的唯象研究

针对湿空气与喷淋水传热传质的问题,在唯象模型和实验分析上做了一些研究。首先以不可逆热力学理论为基础,建立了描述系统内部传热传质的唯象模型。其次针对不同温度下的入口喷淋水和空气影响规律,运用唯象方程组进行分析,发现在本实验的研究条件下,基于唯象模型的推动力研究与实际工程的参数变化趋势基本吻合,说明该理论模型基本可靠,可用于分析湿空气与喷淋水的传热传质研究。

The phenomenological model and experimental analysis on heat and mass transfer of humid air and spraying water in vertical spray chamber

Aiming at the problem of heat transfer and mass transfer of wet air and spray water,hawse did some research on basic theory,phenomenological equation and experimental analysis. First of all,based on the irreversible thermodynamics theory,combining with the basic law,we established a system of phenomenological equations describing the heat and mass transfer. Secondly,the water and air influence law of inlet spraying water and air at different temperatures was analyzed by the phenomenological equations. It is found that under the condition of this experiment research,the theoretical model is basically reliable and the result is consistent with the change of the parameters of the actual project. It can be used to analyze the heat and mass transfer of wet air and spray water.
