摘要

摘要本文研究了螺旋力、旋转和孔隙率对铁磁流体二元混合物中静止对流的外观和对流细胞大小的同时影响。我们确定了系统的瑞利数作为无量纲参数的函数的解析表达式。研究了各参数对系统的影响。考虑基本特性的同时效应,可以确定铁磁流体中对流阈值的演变,进而确定对流单元的大小。通过对所得到的各种结果的分析,我们可以推断出,当同时考虑研究中所考虑的各种影响时,对流是迅速发生还是延迟发生。

Combined Effects of Helical Force and Rotation on Stationary Convection of a Binary Ferrofluid in a Porous Medium.
Abstract This work studies the simultaneous effects of helical force, rotation and porosity on the appearance of stationary convection in a binary mixture of a ferrofluid and on the size of convection cells. We have determined the analytical expression of the Rayleigh number of the system as a function of the dimensionless parameters. The effect of each parameter on the system is studied. The consideration of the simultaneous effect of the basic characteristics made it possible to determine the evolution of the convection threshold in the ferrofluid and then the size of convection cells. The analyzes of the various results obtained allowed us to deduce whether the convection sets in quickly or with a delay when the various effects taken into account in the study are considered simultaneously.
