SUMMARY:Deformation in Porous Media\; squashing paper\, and carbon dioxide
  storage - Duncan Hewitt (DAMTP)

DESCRIPTION:The phenomenon of coupled flow and deformation in porous media
  arises in a huge range of settings\, from everyday household activities l
 ike wringing out a kitchen sponge\, to soil consolidation in sedimentary g
 eology and swelling tissues or oedemas in biology.  In this talk I will di
 scuss mathematical modelling of coupled flow and deformation in porous med
 ia\, with two distinct applications: first\, pressure-driven deformation o
 f underground rock\, and corresponding surface uplift\, around injection s
 ites used in geological storage of CO2\; and secondly\, compression of cel
 lulose pulp suspensions with the aim of extracting water during the paper-
 making process.  In each case I will introduce two-phase theoretical model
 s\, consider and analyse some informative asymptotic limits\, and critical
 ly compare the results to complementary laboratory experiments.
