Non-Fourier heat conduction in IC chip

[1992 Proceedings] Intersociety Conference on Thermal Phenomena in Electronic Systems, 1995
Instead of the classic Fourier equation based on diffusion, a hyperbolic equation based on a wave model has been used to predict the rapid transient heat conduction in IC chips. The peak temperature, spatial difference, and time variation of temperature, which are critical to thermal reliability of the chip, are given and compared with that obtained ...

Non-Fourier heat conductions in nanomaterials

Journal of Applied Physics, 2011
We study the non-Fourier heat conductions in nanomaterials based on the thermomass theory. For the transient heat conduction in a one-dimensional nanomaterial with a low-temperature step at both ends, the temperature response predicted by the present model is consistent with those by the existing theoretical models for small temperature steps. However,

Non-Fourier Heat Conduction in Carbon Nanotubes

ASME 2009 Second International Conference on Micro/Nanoscale Heat and Mass Transfer, Volume 3, 2009
Fourier’s law is a phenomenological law to describe the heat transfer process. Although it has been widely used in a variety of engineering application areas, it is still questionable to reveal the physical essence of heat transfer. In order to describe the heat transfer phenomena universally, Guo has developed a general heat conduction law based on ...

Inverse investigation of non-Fourier heat conduction in tissue

Journal of Thermal Biology, 2016
This paper attempts to describe the heat conduction in tissue using the dual-phase-lag mode. Evaluating the thermo-physical parameters is one of the ways to certify the thermal behavior. As a result, the paper simultaneously and inversely estimates the values of τq, τT and α for bologna based on the dual-phase-lag mode with the measurement data in the ...

Hyperbolic lattice Boltzmann method for three-dimensional non-Fourier heat conduction with phase change

Numerical Heat Transfer, Part A Applications, 2023
The study described the simulation of 3D non-Fourier heat conduction with phase change using a hyperbolic lattice Boltzmann method (HLBM). The equilibrium distribution function was modified for the temperature to develop a new approach for handling the ...

Non-Fourier Heat Conduction in a Nematic Mesophase

Molecular Crystals and Liquid Crystals, 1973
A brief discussion of non-linear (non-Fourier) heat conduction is given. Recent experimental data on nermatic p-anisylidene p-aminophenyl-acetate are also presented to confirm the earlier reported ...

New Interpretation of Non-Fourier Heat Conduction in Processed Meat

Journal of Heat Transfer, 2005
This work uses the “dual phase lag” (DPL) model of heat conduction to offer a new interpretation for experimental evidence of non-Fourier conduction in processed meat that was interpreted previously with hyperbolic conduction. Specifically, the DPL model combines the wave features of hyperbolic conduction with a diffusion-like feature of the evidence ...

Non-Fourier heat conduction/convection in moving medium

International Journal of Thermal Sciences, 2018
Abstract Non-Fourier one-dimensional unsteady heat conduction in a moving medium is investigated by using the Cattaneo-Vernotte- Christov-Jordan (CVCJ) heat flux model for medium speeds less than (sub-critical), equal to (critical), and greater than (super-critical) the thermal wave speed.

Basic Problems of Non-Fourier Heat Conduction

2019
In this chapter, the non-Fourier heat conduction equations along with the boundary and initial conditions are solved for one-dimensional (1D) media with semi-infinite or finite dimensions in Cartesian, cylindrical, and spherical coordinates.
