Effects of Rough Surfaces on Heat Transfer in Channel Flow
채널유동에서 거친벽면이 열전달에 미치는 효과
Abstract
A comparison of fully developed heat transfer and friction factor characteristics has been made in rectangular ducts with one wall roughened by five different shapes. The effects of rib shape geometries and Reynolds number are examined. The rib height-to-duct hydraulic diameter, pitch-to-height ratio, and aspect ratio of channel width to height are fixed at
