Chemical reactions can interplay with hydrodynamic flows to generate chemo-hydrodynamic instabilities affecting the spatio-temporal evolution of the concentration of the chemicals. We review here such instabilities for porous media flows. We describe the influence of chemical reactions on viscous fingering, buoyancy-driven fingering in miscible systems, convective dissolution as well as precipitation patterns. Implications for environmental systems are discussed.This article is part of the themed issue 'Energy and the subsurface'.
化学反应可与流体动力流相互作用,产生影响化学物质浓度时空演化的化学-流体动力不稳定性。我们在此回顾多孔介质流中的此类不稳定性。我们描述了化学反应对粘性指进、混溶体系中浮力驱动指进、对流溶解以及沉淀模式的影响。还讨论了其对环境系统的影响。本文是主题为“能源与地下”特刊的一部分。
