摘要：
In this paper, we report on a scale analysis of natural-convection boundary layers driven simultaneously by thermal and mass diffusion. We derive the scaling laws followed by the temperature and the concentration fields. These are corroborated by numerical investigations in a wide range of parameters. In particular, we predict the existence of flows which are heatdriven even though the amplitude of the solutal convection is dominant.
