Summary
Time-independent natural convection in a two-dimensional, rectangular cavity containing a low Prandtl fluid is solved numerically using a finite-difference method. The numerical results reported in the paper were obtained with the SIMPLER algorithm using the power law scheme for finite-differencing the advection terms in the transport equations. The results for steady-state thermal convection flow in a cavity, having an aspect ratio of four, were obtained with a nonuniform mesh of 101X31. The results show that the flow oscillates, and that the amplitude of the oscillation increases with the Grashof number for both Pr = 0 and 0.015, but the frequency remains the same.
