AbstractThe effects of space of fins, number of tube rows and relative humidity of incoming air on airside performance of wavy fin with hydrophilic coating under dehumidifying conditions were experimentally explored for seven wavy fin-and-tube heat exchangers with hydrophilic coating. The Colburn factor and the Fanning friction were applied to describe airside heat transfer and friction characteristics, respectively.

摘 要：为了确定翅片间距、管排数和入口空气相对湿度等参数对析湿工况下带亲水层波纹翅片空气侧特性的影响，对7个带亲水层的波纹翅片管换热器进行了试验研究，并分别以Colburn换热因子和Fanning摩擦因子来反映空气侧换热和压降特性。

It is shown that the mechanical properties including Young's modulus, tensile strength, critical strain and stress under buckling can be enhanced with the decreasing of intershell spacing. The shear strength can be enhanced by 2-3 orders of magnitude when the intershell spacing is reduced to 20%, which is also dependent on commensuration. Zigzag-type carbon nanotubes have higher shear strength. The axial stress in tubes when the load transferring from outmost tube to inner tube is observed as well.

研究了单壁纳米管束横截面的六方化失稳现象，给出各种管径的面内压力－应变关系曲线；每条曲线都给出一个明显的拐点而且有很强的非线性；线弹性模量与参考构形有关，也受管直径的影响；分析了管束横截面的晶格不稳定性特征，表明晶格的缺陷能够明显的减小临界值；模拟了在不同应变下纳米管束对静水压的反应，发现不同压力下的截面形态不同，在很高压力下相邻管之间会形成化学键。
