An analytical formulation of Bergman–Milton conductivity bounds is used in a different way to obtain rigorous bounds on the real thermal conductivity of a fluid-saturated porous material. These bounds do not depend explicitly on the porosity, but rather on two formation factors—one associated with the pore space and the other with the solid frame.
