Recent developments in Rayleigh-Benard convection

This review summarizes results for Rayleigh-Benard convection that have bee n obtained over the past decade or so. It concentrates on convection in com pressed gases and gas mixtures with Prandtl numbers near one and smaller. I n addition to the classical problem of a horizontal stationary fluid layer heated from below, it also briefly covers convection in such a layer with r otation about a vertical axis, with inclination, and with modulation of the vertical acceleration.
