The phenomenon of coupled flow and deformation in porous media arises in a huge range of settings, from everyday household activities like wringing out a kitchen sponge, to soil consolidation in sedimentary geology and swelling tissues or oedemas in biology. In this talk I will discuss mathematical modelling of coupled flow and deformation in porous media, with two distinct applications: first, pressure-driven deformation of underground rock, and corresponding surface uplift, around injection sites used in geological storage of CO2 ; and secondly, compression of cellulose pulp suspensions with the aim of extracting water during the paper-making process. In each case I will introduce two-phase theoretical models, consider and analyse some informative asymptotic limits, and critically compare the results to complementary laboratory experiments.
