Abstract

In this paper, the effect of configurations of rotating cylinders in a vented cavity with inlet and outlet port on the flow field and heat transfer enhancement of forced convection of Al2O3/Cu-water hybrid nanofluid flow in the laminar regime is numerically investigated. In this study, the influence of parameters as configurations of cylinders (A, B, C, and D), as well as the rotational velocity of cylinders (from -10 to +10), Reynolds number (from 100 to 500), and the volume fraction of nanoparticles (from 0.5% to 3%) on the flow field and heat transfer are studied. Results indicate that the average Nusselt number and the Performance Evaluation Index for configuration D are higher than other configurations. Also, it is obvious that by increasing the rotational velocity of cylinders, Reynolds number, and the volume fraction of nanoparticles, the Performance Evaluation Index increases. Also, by rotating the cylinders in the counterclockwise rotation direction with respect to the clockwise rotation direction, the η increases about 1.30. The results show that Al2O3/Cu-water hybrid nanofluid causes heat transfer enhancement compared to the Cu-water nanofluid and it increases the Performance Evaluation Index compared to the Al2O3-water nanofluid.
