Cooling of a plane slab of an absorbing gray medium with simultaneous conduction and radiation heat transfer

A method for calculating transient heat transfer by radiation and conduction in a slab of a gray absorbing medium is discussed. The results are given from calculations of the cooling of a slab having a transparent upper boundary and a diffusely reflecting lower boundary in contact with an opaque material.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 41, No. 5, pp. 874–879, November, 1981.
