摘要

摘要: 对流现象广泛存在于恒星和行星里. 在地球上, 对流现象在诸如大气、海洋、地核和地幔等众多动力学系统中起着重要作用. Rayleigh-Bénard (RB) 湍流热对流系统是从这些复杂的自然现象中抽象出来的研究对流问题的经典流体力学模型. 本文主要从湍流传热、羽流、大尺度流动结构、速度和温度脉动的小尺度统计和非传统RB 对流等几个方面着重评述近年来RB 对流的若干研究新进展, 并对今后的研究做出展望.

Abstract: Turbulent Rayleigh-B閚ard (RB) convection, a fluid layer heated from below and cooled from above, has become a paradigm for the study of general convection phenomena that occurs ubiquitously in nature and in many engineering applications. This paper presents an overview of recent advances in the following major areas of RB convection: turbulent heat transport, thermal plumess, large-scale circulation, and small-scale properties of velocity and temperature fields. A brief description of recent developments in the studies using non-traditional RB configurations is also presented. We end by pointing out main remaining issues and challenges and giving an outlook on the future development.
