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.
