Abstract: The experimental investigation of heat transfer and friction factor characteristics of double pipe heat exchanger using aluminum oxide water based nanofluid. In this present study the double pipe heat exchanger for a plain tube the heat transfer from hot water to cold water was experimentally investigated. This investigation also to find the Nusselt number, heat transfer coefficient, and Reynolds number. The experimental value of plain tube with water and Al2O3 was obtained from the experimental work and these two statistical data were compared with the results. The results shows that the heat transfer rate enhancement of induced with the nanofluids water based flow has give more heat transfer compared to the plain water. The Reynolds numbers were varied in the range of 5710 to 18366. The data obtained from the experimental value were compared with CFD simulation analysis. The performance of heat transfer characteristics of aluminum oxide nanofluids was enhanced compared with smooth plain water used. The experimental value of the heat transfer and friction factor characteristics was well bonding with simulation value of CFD analysis.

Keywords: Heat transfer, Nanofluid, computational fluid dynamics

I. INTRODUCTION

Heat exchangers have used for several industrial and engineering applications to improve the performance of heat exchanger devices for enhancement of heat transfer. A majority of heat exchangers used in chemical processing plants, air conditioning equipment, thermal power plants, etc. The heat transfer augmentation techniques are generally classified into three categories namely, Active techniques, and Passive techniques and compared techniques. Sami et al. [1] have investigated in a circular tube fitted with Quadrant – cut twisted tape inserts by using CFD analysis of the heat transfer and friction factor characteristic.
