Abstract

The flow structure and heat transfer in inclined two-dimensional differentially heated square cavities is investigated via numerical simulation. It is shown that the basic flow structure is changed when the cavity is inclined such that the heated wall is below the cooled wall, with attached jet/plumes forming adjacent to the adiabatic walls, rather than diffuse intrusions as for the non-inclined cavity. At a specific angle of inclination, the flow undergoes a bifurcation so that the fully developed flow is unsteady and single mode, with a further increase in inclination leading to multi-modal and then broad banded chaotic flow. The Nusselt number is obtained and plotted against the inclination angle to determine the effect of inclination on the total cavity heat transfer.
