Local Thermal Non-Equilibrium Models in Porous Media: A Comparative Study of Conduction Effects

Anna Mareike Kostelecky, Ivar Stefansson, Carina Bringedal +3

Instantaneous heat transfer between different phases is a common assumption for modeling heat transfer in porous media, known as Local Thermal Equilibrium (LTE). This assumption ma…
