The present thermal science and beyond

Abstract

The Fourier law and its various modifications have been widely used to study various thermal problems with great success, but many thermal phenomena cannot yet be explained, for example, the effect of pore size and distribution on the heat transfer of a porous medium, the extremely high thermal conductivity of metasurfaces, and the moisture transfer through a fabric. This short article shows the current state of thermal science for modern science and technology, and its challenge in the future.
