【摘要】 Rayleigh-Benard(RB)对流是研究非平衡对流的稳定性、非线性动力学特性及湍流形成机理的典型模型之一。在介绍RB对流研究方法的基础上,论述了其最新研究进展:混合流体RB对流运动的稳定性及其非线性动力特性;RB对流与水平流动相耦合时的非线性动力特性。最后提出了有待进一步研究和探讨的问题。更多还原

【Abstract】 Rayleigh-Benard convection is one of typical models for studying the stability,nonlinear dynamics of convection and the mechanism of forming turbulent flow.Based on the introduction to research on RB convection method,this paper deals with its latest research progress,the stability of Rayleigh-Benard convection motiom in binary fluid mixtures,and the non-linear dynamic behaviors of Rayleigh-Benard convenction coupling with horizontal flow.Finally,this paper suggests some problems worth further studying.更多还原
