【摘要】 主要研究了在二维矩形腔体中,不同条件对Rayleigh-Benard对流时空结构影响。首先分析了没有水平流速作用下,Rayleigh-Benard对流的对流特性;其次,分析了具有水平流速作用下的Rayleigh-Benard对流的特性;最后,分析了在变调流速作用下,Rayleigh-Benard对流的特性。总结得出对流结构的动力学特性和时空结构。更多还原

【Abstract】 In this paper,we focus on the influence of different conditions to the spatiotemporal structure of Rayleigh-Benard Convection in a rectangular channel which is filled with water.First,the characteristic of Rayleigh-Benard Convection without lateral flow is analyzed.Secondly,the characteristic of Rayleigh-Benard Convection with lateral flow is introduced.Finally,the characteristic of Rayleigh-Benard Convection with modulation velocity is also discussed.From these results,the dynamic structure characteristic and spatiotemporal of the convection can be acquired.更多还原
