Local thermal non-equilibrium effects arising from the injection of a hot fluid into a porous medium
TL;DR: In this paper, the effect of local thermal non-equilibrium on the infiltration of a hot fluid into a cold porous medium is examined, and it is found that the thickness of the advancing thermal front is a function of the governing parameters rather than being independent of them.
