Abstract: Abstract:Abstract Our aim in conducting the numerical simulation of laminar flow in a cubical container is to explore into the flow structure subjected to a disk rotation on the roof of the container. To this end, we have applied the topology theory to analyze skin-friction lines or limiting streamlines to elucidate the kinematically possible vortical flow structure. For this study, four different Reynolds numbers in the range of Re=500–2000 were considered, with emphasis on the case with Re=1000. Revealed from the analysis is that the secondary flow structure emerges as a result of a plane disk rotating motion. The two-cell counter-rotating flow pattern in the plane perpendicular to the rotating disk is spatially varying due to the four corners present in the cubical container. We have also depicted the vortical flow structure in terms of vortex cores which provide more details about how mixing of the flow can be achieved through a simple plane disk rotation.
