ABSTRACT
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. © 2000 American Institute of Physics.

    The potential flowfield surrounding a vortical flow domain is investigated. The vortical region is restricted to a three-dimensional finite domain in an unbounded incompressible viscous fluid that is at rest at infinity. The vector streamfunction of the flow is obtained by the integrals over the...

    The stability of the channel flow of two fluids of different viscosities with a mixed layer in between is demonstrated to be qualitatively different from both interface dominated flows and stratified flows. More important, this flow displays unexpected changes in stability when the mixed layer...
