Abstract

The objective of this work is to investigate numerically the single phase natural convective heat transfer in a cavity with baffle utilizing Al2O3-water nano fluid. The study is carried out numerically for a range of baffle heights, h=0.2, 0.5 and 0.8. Results are presented in the form of streamline and isotherm plots. The results show that heat transfer decreases considerably with increasing partition height. For the two-baffle cavity, as the height of baffle increases, separation in the vortices is seen and there is only conduction heat transfer between two baffles. Compared to the top-attached cavity, for the top-attached cavity, streamlines and isotherms are symmetric to the central line. For the two-baffle cavity, all the plots are symmetric to the central line.
