Abstract: The applications of artificially roughened duct or surfaces are being used by researchers to enhance heat transfer rate from heat transferring surface to working fluid. There are different techniques to analyze the heat transfer mechanism those are explained in this literature. The present work was undertaken with the objectives of extensive investigation on the 900 shaped ribs as artificial roughness on the surface of duct. Experimental setup for heat transfer and pressure lose have been design and developed. Data were collected for local heat transfer and pressure loss of these artificially roughened ducts. Results of artificially roughened duct have been compared with those of a smooth duct under similar flow condition to determine heat transfer and friction factor.
Keywords: Heat Transfer, Friction Factor.
