Numerical Investigation of heat transfer and pressure drop for circumferential finned tube heat exchangeris presented in this paper considering Al2O3 Nano fluid as base fluid. The required thermo-physical properties weremeasured and used in CFD using UDF (User Defined Functions). The results of numerical simulation are comparedwith that of experimental results in order to verify the accuracy of code used in CFD.Further numerical simulation is carried out for 2% volume fraction of Nano particles at different Reynoldsnumber. Thermo-Hydraulic Performance factor a measure both heat transfer and pressure drop has decreased asReynolds number augmented. But for all Reynolds number Thermo-hydraulic performance factor obtained proves us thatusage of Nano fluid is beneficial.
