Experimental investigation of local heat transfer in a square duct with continuous and truncated large ribs

Wang, Lei LU and Sundén, Bengt LU (2004) ASME International Mechanical Engineering Congress and Exposition, 2004 375(1). p.589-597
Abstract
Repeated ribs are frequently employed to promote turbulence and to enhance heat transfer in various ducts. In the present study, liquid crystal thermography was applied to the study of heat transfer from a square channel having one surface heated at uniform heat flux and roughened by repeated ribs. The continuous and truncated ribs, having square sections, with height-to-hydraulic diameter ratio of 0.15, were deployed normal to the mainstream direction of flow. Detailed distributions of the local heat transfer coefficient were obtained at various Reynolds number within the turbulent flow regime. Averaged data were calculated in order to evaluate the augmentation of heat transfer by the presence of different ribs. Copyright
