Numerical investigation of natural convection heat transfer in a cavity utilizing Al2O3-Water nanofluid: Effect of baffle height
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.
