Convective diffusion of heat is a problem which arises in many areas. Since most thermal transport situations involve more than one material insulation, supports, etc., the treatment of composite regions is of interest. In certain systems, namely, those involving chemical or nuclear reactions, heat generation may be either localized or distributed. In this paper a general analytical treatment of this problem is made by using a double Fourier series technique involving an extended orthogonality concept. This treatment is then applied to the solutions of heat transfer situations arising in electrochemical energy conversion systems. Experimental temperature profiles are presented which test the theory.
