摘要
本文用三次样条方法对充满饱和多孔介质的方腔的底部加热时出现的对流分叉现象进行了数值模拟,得到三个分叉点,观察到了分叉点邻域内流动发展状态,对稳定性与挑动幅度关系做了初步的探讨。
The convective bifurcation of fluid through porous media in a square cavity heated from below is simulated numerically by the cubic spline method. This paper gives three critical points and presents the preliminary results for conditional stability.
