In-Use Determination of the Dynamical Thermal Properties of Multilayer Objects

Thermal response of multilayer objects to an arbitrary variation of temperatures of the ambient air are considered in terms of the step-response solutions (STS's). A procedure of calculation STS's with use of fast Fourier transform is described. A method of determination of STS's of multilayer objects in working conditions in the case of arbitrary varying temperatures of the ambient air is considered. An application of the developed technique to calculation of STS's of a model 3-layer object is demonstrated.
