Approximate Analytical Solution of Heat and Mass Transfer Processes in Packed-type Cross-flow Liquid Desiccant System and Its Experimental Verification

通过将交叉流填料式液体除湿系统的热质传递过程抽象为空气和溶液均可以横向混合的 ,并且可将两流体的传递过程分别化为一维来分析的问题进行处理 ,建立了描述该过程的数学模型 .经合理简化 ,推导出该数学模型的一种近似解析解 。

In this paper,it is assumed that both air and liquid desiccant solution can mix in their cross direction in packed type cross flow liquid desiccant system.So it can be considered that the parameters of air and solution only change in their flow direction.The mathematical model descrtbing the heat and mass transfer processes of this system is established.An analytical solution is obtained under some appropriate simplified conditions.The analytical model also compares with the experimental data.
