 In the present study, the hydrodynamic and heat transfer characteristics of compact fin and tube heat exchangers have been investigated numerically. The aim is to analyze the influence of operating conditions and the geometry parameters of compact heat exchanger to design more efficient heat transfer device. Fin spacing and fin thickness are the geometrical parameters. The over-fin fluid velocity or Reynolds number is used as the parameter of operation. Here in this work it finds the effect of different material, fin thickness and fin spacing on heat transfer enhancement of the compact heat exchanger. Here in this work four different Reynolds number that is 2622.96, 5248.98, 7873.25 and 10497.96 were considered to analyze the effect of different velocity of fluid. It also analyzed the effect of different materials used for the construction of Fin and tube, in this work three different steel alloys that is GH2132, GH3044 and S66280 were considered for the analysis in which GH3044 shows the better heat transfer as compared to other. For GH3044 material heat transfer rate is 15 % more than the GH2132 material. Whereas domain having 0.8 mm fin spacing shows 5 % increase in heat transfer as compared to 1.1 mm fin spacing.
