Abstract
The experimental investigation of friction factor and heat transfer characteristics of double pipe heat exchanger using aluminum oxide water based nanofluid. In this present study the heat transfer from hot water to cold water of the double pipe heat exchanger for a plain tube was experimentally investigated. This investigation also to find the heat transfer coefficient, Nusselt number, 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 5000 to 18000. The data obtained from the experimental value were compared with CFD simulation analysis. The performance of heat transfer characteristics of aluminum oxide nanofluid 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.
