Author: Xu Feng, Cui Huimin
Abstract:
The study of natural convection in a differentially heated cavity is of practical significance in nature and industry. It is of scientific value to review the studies of natural convection flows, their flow properties, dynamical mechanisms, dimensional controlling parameter dependencies and heat transfer driven by the horizontal temperature gradient in the cavity. As shown by previous studies, the development of natural convection suddenly enforced by the horizontal temperature gradient between the sidewalls of the cavity includes an initial stage, a transitional stage and a steady or a quasi-steady stage. The transient flows in the different stages are determined by the Rayleigh number, the Prandtl number and the aspect ratio. The flow in the steady or quasi-steady stage could be a steady laminar, a periodic or a turbulent flow. In addition, the studies of instability and turbulence of natural convection in the cavity are reviewed, and the prospects for the study of natural convection in the cavity are presented.
