Convective instabilities and transport properties in horizontal fluid layers

Abstract

This paper concerns the analysis of convective instabilities and fully developed transport properties in Benard convection. The onset of convective instabilities driven by surface-tension variations and buoyancy forces is analyzed theoretically by using the propagation theory we have developed. Based on these stability criteria, the subsequent transport correlations of fully developed buoyancy-driven convection in horizontal fluid layers are suggested. It is found that the present predictions are compared favorably with existing experimental results.
