Periodic oscillatory flows in low Prandtl-number fluids are numerically characterized in this study. A mathematical model is developed to solve the three-dimensional mass and momentum conservation equations using a control-volume algorithm. For various aspect ratios, the second critical Rayleigh number is determined. For an aspect ratio (length/height) of 0.25, macroscopic oscillations are unmistakably observed; while as the aspect ratio is increased, oscillations tend to dampen.
