DESCRIPTION:Speakers: Mats Brun (University of Bergen)\nMotivated by geoth
ermal energy storage in the subsurface\, we undertake a formal derivation
of a linear poro-thermo-elastic system within the quasi-static framework.
This derivation is based upon the well known derivation of the quasi-stati
c poroelastic equations (also known as the Biot consolidation model) from
the micro structure\, except that we now include energy conservation equat
ions in the micro-scale model. These are coupled to the fluid/structure mo
del by using linear thermo-elasticity for the solid structure instead of t
he usual linear elasticity. The resulting upscaled system is similar to th
e linear poro-elastic equations\, but with an added conservation of energy
equation\, fully coupled to the momentum and mass conservation equations.
We start at the pore scale\, and apply the technique of homogenization to
derive the upscaled model in the case of periodically distributed pores.
Assuming the homogenization ansatz holds true\, we obtain a fully coupled
system of equations on the macro-scale accounting for the effects of geome
chanics\, heat transfer\, and fluid flow within a fully saturated porous m
aterial.\n\nhttps://events.interpore.org/event/2/contributions/102/
