Flow and Temperature Field in Fin Tube Heat Exchanger through the Addition of Convex Strip Vortex Generators

Abstract

Enhancement of heat transfer in fin and tube heat exchangers using vortex generators has been carried out by many researchers because of the effectiveness of this method. Therefore, the present work is focused on observing the effect of varying the number of convex-strips vortex generators on heat transfer improvement and their impact on pressure losses in heat exchangers. Numerical simulations by varying the number of convex strips of 4, 8, 12, 16, 20, 24, and 28 installed around the heated tubes were carried out. The k-ε turbulence model is determined by the Reynolds number range from 3,438 – 15,926. The results of this study conclude that fins with 24 convex-strips show the most uniform temperature distribution than those of the other convex-strips.
