The current research investigates pin finned tube heat exchanger was studied numerically having conventional circular fin and fins with extended members. The numerical analysis is conducted using ANSYS CFX software and CAD model is developed using Creo design software. The Nusselt number and friction factor are evaluated for both design configurations at different air inlet velocities of 5m/s, 7m/s, 9m/s and 11m/s. Standard K-epsilon turbulence model is used for CFD analysis which gives reasonably good predictions for fluid flow involving complex geometries. The Nusselt number and friction factor are determined for different Reynolds number for both design configurations. The CFD analysis has shown that fins with extended members show augmentation in heat transfer and Nusselt number with incorporation of extended members of pin finned heat exchanger.
