| 摘 要： | 为考察吸附床内不同管数和管径对传热的影响,分别设定吸附床的换热面积或填充量为定值,改变传热管的直径及管数,建立了吸附床三维几何模型,利用FLUENT软件进行数值模拟计算,得到吸附床温度场变化规律.结果表明:当吸附床换热面积或填充量一定时,随着换热管数目增多,直径减小,同一时刻吸附床轴向和径向各点温度上升更快,分布更均匀,强化了传热;质量流量对床层温度没有大的影响;并对原吸附床结构进行改进,由原来的5根Ф32×3 mm的传热管和12根Ф10×1mm传质管改为Ф10×1 mm的50根传热管和23根传质管,其填充量变化不大,但换热面积却由0.58 m2增加为1.11 m2,床层温度分布更均匀,强化了传热,缩短了循环周期.

| Abstract: | To study the influence of diameter and number of the heat transfer tube on the heat transfer,the parameters of the adsorbent bed were calculated when the diameter and number of the heat transfer tube were changed in the same heat transfer area or the same volume of the adsorbent bed.A three-dimensional structure model of the adsorbent bed is established.Temperature field is numerically investigated by using FLUENT.It is shown from results that the temperature of the radial direction and axial direction sect... |
