Causality in non-fourier heat conduction

open access: yesJournal of Physics Communications, 2022
Abstract We present a study of the causal response of non-Fourier heat conduction by introducing a dispersive generalized thermal susceptibility and show it obeys Kramers-Kronig relations. In particular, we discuss the Cattaneo-Vernotte and the dual-phase lag models.

Numerical analysis of non-Fourier heat conduction dynamics in the composite layer

open access: yesJournal of Mechanical Engineering and Sciences, 2023
This paper presents the numerical analysis of non-Fourier heat conduction in thin composite layers under asymmetrical boundary conditions. In the thermal barriers such as steam and gas turbine blades, thin film coating are used to protect the blade from

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.

A renovated Jaffrey-Hamel flow problem and new scaling statistics for heat, mass fluxes with Cattaneo–Christov heat flux model

open access: yesCase Studies in Thermal Engineering, 2023
In dire situations, such as the restricted spatial scale in nanoparticle systems and the analogous analysis of non-Fourier heat conduction and conventional heat conduction, the transmission of heat and momentum will exhibit non-linear and nonlocal ...

Using the Lattice Boltzmann Method for the numerical study of non-fourier conduction with variable thermal conductivity [PDF]

open access: yesJournal of Heat and Mass Transfer Research, 2018
The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained.

An analogy analysis between one-dimensional non-Fourier heat conduction and non-Newtonian flow in nanosystems [PDF]

open access: yes, 2021
The transport of heat and momentum will exhibit non-linear and nonlocal behavior in extreme conditions, including the limited spatial scale in nanosystems. In this work, we present an analogy analysis between non-Fourier heat conduction and non-Newtonian
