Non-Fourier Heat Conduction of Nano-Films under Ultra-Fast Laser. [PDF]

open access: yesMaterials (Basel), 2023
The ultra-fast laser heating process of nano-films is characterized by an ultra-short duration and ultra-small space size, in which the classical Fourier law based on the hypothesis of local equilibrium is no longer applicable.

Emergence of Non-Fourier Hierarchies [PDF]

open access: yesEntropy, 2018
The non-Fourier heat conduction phenomenon on room temperature is analyzed from various aspects. The first one shows its experimental side, in what form it occurs, and how we treated it.

A New Thermal Model for Predicted Discharge Craters in Micro/Nano-EDM Considering the Non-Fourier Effect

open access: yesCrystals, 2022
Micro/nano-electrical discharge machining is an alternative preparation method for surface micro/nano-structures, but it is difficult to precisely control the size of the micro/nano-structures due to its unclear material removal mechanism.
