Review of Heat Transfer Enhancement Techniques of W Ribs

Jayshri S. Gulave, Prof. Parag S. Desale

Abstract: This paper is a review about the early studies on the heat transfer enhancement in a rectangular duct with rib turbulators. Heat transfer enhancement has been always a significantly interesting topic in order to develop high efficient, low cost, light weight heat exchangers. There are different kinds of ribs to enhance the heat transfer rate such as V-ribs (simple and broken v-ribs), triangular and rectangular ribs, segmented and circular ribs. W Ribs on the opposite walls of internal cooling passages of gas turbine blades are often used for heat transfer enhancement. Rib Turbulators is an efficient and economic tool in heat transfer enhancement. Combination of various ribs and duct artificial roughness provided promising results. In case of using various rib type, heat transfer enhancement was depend on no. of ribs and height of ribs and various arrangement of ribs.

Keywords: Heat transfer Enhancement, Ribs, V and Broken v ribs, W-Ribs
