Abstract

A numerical investigation has been carried out for a range of flow and geometrical parameters in order to analyze the effect of transverse perforated baffles attached on the heated wall of rectangular duct on heat transfer and friction factor. An increase in heat transfer and friction loss over a smooth surface has been observed for duct having perforated baffles as a roughness element. Numerical results have been used to develop the Nusselt number and friction factor correlations as a function of flow and geometrical parameters for predicting performance of the system having investigated the type of roughness elements. doi: 10.14456/WJST.2014.33

基于数值的带横向穿孔折流板粗糙矩形管道传热与摩擦系数相关性研究

为了分析矩形风管受热壁上加装横向多孔折流板对传热和摩擦系数的影响，对一系列流动参数和几何参数进行了数值研究。在光滑表面上传热和摩擦损失的增加已经被观察到，对于有穿孔挡板作为粗糙元件的风管。在研究了粗糙度元素的类型后，利用数值结果建立了努塞尔数和摩擦系数作为流动和几何参数的函数的相关性，用于预测系统的性能。doi: 10.14456 / WJST.2014.33
