Fuel rod model based on Non-Fourier heat conduction equation

Annals of Nuclear Energy, 2009
Abstract In this paper we explore the applicability of a fuel rod mathematical model based on Non-Fourier transient heat conduction as constitutive law for the Light Water Reactors transient analysis (LWRs). In the classical theory of diffusion, Fourier law of heat conduction is used to describe the relation between the heat flux vector and the ...

Non-Fourier phonon heat conduction at the microscale and nanoscale

Nature Reviews Physics, 2021
The description of phonon heat conduction has typically been based on Fourier diffusion theory. However, over the past three decades, a host of interesting phonon transport phenomena beyond the Fourier diffusion picture have drawn much attention. Although most of the studies focused on classical size effects that lead to reduced thermal conductivity ...

Analysis of non-Fourier heat conduction using smoothed particle hydrodynamics

Applied Thermal Engineering, 2011
Abstract A gridless discretization technique namely smoothed particle hydrodynamics (SPH) is used to analyze non-Fourier heat conduction. First, the technique has been employed to compute the temperature evolution in a slab subjected to an initial non-uniform temperature distribution with both the ends insulated.

Dynamical Governing Equations of Non-Fourier Heat Conduction

2015
Thermal energy has its corresponding equivalent mass according to Einstein’s mass–energy equivalence, which is termed as thermomass. The thermomass theory established the continuous governing equation for the non-Fourier heat conduction. The mass balance equation of thermomass gives the energy conservation equation while the momentum balance equation ...

Analysis of Non-Fourier Conduction Waves from a Reciprocating Heat Source

Journal of Thermophysics and Heat Transfer, 1997
The temperature proe les that result when a point heat source is swept back and forth along a rod in which heat travels at e nite speed are examined. Green’ s functions are used to solve the hyperbolic heat equation for cases in which the source speed is half, equal to, and double, the natural thermal wave speed of the rod material.
