Notes:
Previous studies have shown that heat transport by horizontal conduction in thermal displacement processes in porous media has a stabilizing effect on condensation fronts. This paper expands the stability analysis by also including the description of heat transfer lateral heat losses by conjungate (vertical) conduction. A marginal stability condition is derived in terms of a parameter Λ representing the relative magnitude of heat transfer by conjugate conduction. It is shown that lateral heat losses ask a significant stabilizing effect on the front. This effect should be important in thermal oil recovery processes such as steam injection and in-situ combustion.
