There are different methods to augment heat transfer like incorporating swirl-flow devices with different geometric arrangements which could create rotating flows. Geometric arrangements include use of coiled tubes, vortex generators and twisted tapes being used to increase heat transfer rate. These geometric configuration finds its application in various industrial components and heat exchangers, HVAC systems. This research investigates application of nano fluids Al2O3/water nano fluids in heat exchanger with dual twisted tapes using numerical method. The numerical investigation is conducted using techniques of Computational Fluid Dynamics. The CAD model is developed using Creo design software and the CFD simulation is conducted using ANSYS CFX. RNG K epsilon turbulence model is used for analysis which is more suited for flows involving swirl.
