在本文中,我们研究了水平流体层中有限振幅流动的平衡状态,两个刚性边界之间存在不同的加热。纳维-斯托克斯方程的解是通过用于评估朗道常数的微扰方法和牛顿-拉夫森迭代方法获得的,该方法是由在无穷小扰动的线性稳定性阈值之上分叉的解的傅立叶展开产生的。在临界瑞利数附近比较了这两种不同的对流评估方法所获得的结果。我们发现,对于较小的普朗特数,两种方法的差异很明显。
In this paper we examine the equilibrium states of finite amplitude flow in a horizontal fluid layer with differential heating between the two rigid boundaries. The solutions to the Navier–Stokes equations are obtained by means of a perturbation method for evaluating the Landau constants and through a Newton–Raphson iterative method that results from the Fourier expansion of the solutions that bifurcate above the linear stability threshold of infinitesimal disturbances. The results obtained from these two different methods of evaluating the convective flow are compared in the neighborhood of the critical Rayleigh number. We find that for small Prandtl numbers the discrepancy of the two methods is noticeable.
