| 摘 要： | 基于合理的假设条件,建立了同时考虑轴向导热、质扩散以及多孔结构的数学模型,对硅胶基复合干燥剂转轮的传热传质过程进行了数值模拟计算。计算结果与实验数据误差在10%以内。利用该数学模型分析了复合干燥剂转轮结构参数及运行参数对最优转速的影响。研究发现转轮的厚度和再生角度对最优转速影响较大,当复合干燥剂转轮厚度控制在100 mm,再生角度为90°时,转轮性能最优。

| Abstract: | Based on the reasonable assumption,a numeric model describing the process of axial heat conduction and gas-solid two phase diffusion within porous composite desiccant wheel was set up and solved.The difference between computed and measured values was less than 10%.The impacts of its structure parameters and operating parameters on the optimized rotation speed were analyzed with this model.The results show that the thickness and regeneration angle of desiccant wheel have great effects on the optimized rotati... |
