摘    要:本文在文献[2]的基础上,进一步从理论上研究了环形多孔介质内自然对流中的分叉现象。通过稳定性分析,得到了临界分叉点的理论估计值。结果表明本文所采用的线性稳定性分析方法在研究这种分叉现象时是有效的.从而为一些更复杂的分叉现象的理论研究提供了一条可能的途径。

关 键 词:自然对流,分叉,线性稳定性分析

Abstract:This paper deals with the predication of the onset of bifurcation phenomenon in natural convection in a horizontal porous annulus heated from the inner surface.The critical bifurcation Rada number is obtained by linear stability analysis method. Suchanalysis shows that this kind of bifurcation problem can be studied by linear stability analysis method and this method is an effective approach to the solution of some more complexbifurcation problems.
Keywords:natural convection bifurcation linear stability analysis method
