The Stability

We present the results of a combined theoretical and experimental study of the stability of a uniformly stratified fluid bounded by a sidewall moving vertically with constant velocity. This arrangement is perhaps the simplest in which boundary effects can drive instability and, potentially, layering in a stratified fluid. Our investigations reveal that for a given stratification and diffusivity of the stratifying agent, the sidewall boundary-layer flow becomes linearly unstable when the wall velocity exceeds a critical value. The onset of instability is clearly observed in the experiments, and there is good quantitative agreement with some predictions of the linear stability analysis.

The Waves

A theoretical and experimental study is presented of the longitudinal propagation of disturbances in an unstably stratified fluid layer, especially those generated by periodic temperature fluctuations at a side boundary. The most important characteristics of the waves at both supercritical Rayleigh numbers, in the presence of steady roll-like cells, and subcritical Rayleigh numbers are determined.
