This work studies the heat equation in a two-phase material with spherical inclusions. Under some appropriate scaling on the size, volume fraction and heat capacity of the inclusions, we derive a coupled system of partial differential equations governing the evolution of the temperature of each phase at a macroscopic level of description.
The coupling terms describing the exchange of heat between the phases are obtained by using homogenization techniques orignitating from [D. Cioranescu, F. Murat: College de France Seminar vol. 2. (Paris 1979-1980) Res. Notes in Math. vol. 60, pp. 98--138. Pitman, Boston, London, 1982.]
