A two-port network formalism for 3D heat conduction analysis in multilayered media

This paper demonstrates that the two-port network formalism, commonly used to treat one-dimensional heat flow problems in composite slabs, is also applicable to three-dimensional problems in the context of integral transform methods. This provides easy calculation means for temperature and heat flux distributions within multilayered systems. Both spectral and superposition methods are thus presented as examples in a variety of cases of interest to engineers
