波纹

The effects of space of finsnumber 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 characteristicsrespectively.

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。

Furthermore the performances of heat transfers including corrugate plate, tube and fin-tube were compared under the same conditions. The results show that when the air frontal velocity is between 2.45 and 4.1m/s, the overall heat-transfer coefficient of plate heat exchanger ranges from 100 to 160 W/m^2/ equal to one sixth of that of fin- tube cooler based on tube outside area, which is about 70% higher than that of tube cooler. The volumetric heat transfer capacity of plate cooler is 1.5 times as that of fin-tube cooler and 15 times as that of tube cooler. The heat transfer capacity of per unit power of plate cooler is 5.5 times as that of tube cooler and similar results for fin-tube cooler.

在相同工况下，比较了波纹板式、光管式和翅片管式空冷器的性能指标，结果表明：迎面风速在2.45~4.1m/s之间，波纹板式空冷器传热系数达到100~160W/平方公尺/℃；约比光管式提高70%，但只有以管束外表面为基准的翅片管式传热系数的六分之一；板式空冷器单位体积换热量约是翅片管式空冷器的1.5倍，是光管式的15倍；板式空冷器单位功耗换热量约是光管式空冷器的5.5倍，而翅片管式空冷器与光管式空冷器则相差不大。

A detailed description of the implementation of boundary condition and discretization of source terms in curvilinear coordinates has been provided.

波纹管内流动和换热规律的实验研究及数值模拟波纹管是强化换热的一种十分有效的方式，它在紧凑式换热器中得到了广泛的应用。

Among the most common compound molding s are the projecting, double-curved cyma recta or ogee, often used as a crown molding , and the cyma reversa, used for crown or base.

最常见的复合式线脚是突出的双曲正波纹线或S形线，通常用作拱顶线脚，而反波纹线则用于拱顶或拱基。
