Abstract
The Guyer–Krumhansl equation is an extension to the classical Fourier law that is particularly appealing from a theoretical point of view because it provides a link between kinetic and continuum models and is based on well-defined physical parameters. Here we show how, subjected to a specific boundary condition analogous to the slip conditions for fluids, the Guyer–Krumhansl equation yields promising results in predicting the effective thermal conductivity of nanowires with circular and rectangular cross-sections.
