Heat transfer studies and flow visualization of a rectangular channel with an offset strip fin array

Abstract

In this study, the offset strip fin array in a liquid flow liquid flow through module was examined. The study used a model of the heat exchanger which is ten times larger than the actual model used in electronics cooling. Water and Brayco Micronic 889 Polyalphasolefin were used as the working fluids in order to determine the Reynolds number and Prandtl number effects on the Colburn j factor. Also, flow visualization were experiments were performed to determine the flow characteristics of the offset strip fins for laminar flow.
