Abstract

A general solution of the inverse problem of nonstationary heat conductivity in multilayer objects based on Fourier expansion of time dependencies of the surface temperatures is considered. An example of a thermophysical properties determination in the case of a three-layer object is presented. An influence of the measuring equipment precision on the determined values of the characteristics is investigated. It is illustrated that the presented method provides a satisfactory precision in a wide range of amplitude values of measuring equipment noise.
