A method was developed to determine the thermophysical properties of a two layered composite slab whose one exposed surface was subjected to a known temperature history and whose other surface to convective and radiative heat exchange. The physical properties to be determined were the thermal conductivity and diffusivity of one of the two layers and the contact conductance between the two layers, the coefficient of convective surface heat transfer, and the absorbtivity of thermal radiation energy applicable to one exposed surface of the slab. The developed method was used to determine property values of the insulated wall of a still retort.
