The object of this study is to investigate the question of convective movement of a reacting solute in a viscous incompressible occupying a plane layer in a saturated bidisperse porous material. Among the characteristics of a bidisperse porous medium are pores, called macropores, but porosity in the solid skeleton, known as microporosity, arises where there are cracks or fissures in that skeleton. In this paper, a comparison is made between the thresholds for linear instability and those obtained from a global nonlinear energy stability analysis.

化学反应对双分散多孔介质中对流的影响

这项研究的目的是研究在饱和的双分散多孔材料中，反应性溶质在粘性不可压缩层中占据平面层的对流运动问题。在双分散多孔介质的特征中有称为大孔的孔，但在固体骨架中的孔隙（称为微孔）出现在该骨架中存在裂纹或裂缝的地方。在本文中，比较了线性不稳定性的阈值和从全局非线性能量稳定性分析获得的阈值。
