Abstract

Numerical Investigation of heat transfer and pressure drop for circumferential finned tube heat exchanger
is presented in this paper considering Al2O3 Nano fluid as base fluid. The required thermo-physical properties were
measured and used in CFD using UDF (User Defined Functions). The results of numerical simulation are compared
with 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 Reynolds
number. Thermo-Hydraulic Performance factor a measure both heat transfer and pressure drop has decreased as
Reynolds number augmented. But for all Reynolds number Thermo-hydraulic performance factor obtained proves us that
usage of Nano fluid is beneficial.
