Transient heat conduction in composite systems

Abstract:- This paper presents a new method for the determination of the transient heat conducting processes occurring in composite systems of different heat conducting layers. The problems of this type are treated by the aid of the Laplace transformation in the literature [3], [4]. The classical inversion methods are no applicable for N> 2 [1]. This new method is based on the Papoulis-Berg inversion method [2], [5]. The most advantage of the method lies in the fact that it is applicable for linear composite heat conducting systems of any number of layers, for constant heat conduction coefficient.
