Non-Fourier phase change heat transfer in biological tissues during solidification
Heat and Mass Transfer, 2012The phase change in biological tissues during a freezing process is simulated by hyperbolic and parabolic heat equations with temperature-dependent enthalpy. It is observed that the experimental results are in a good agreement with that the calculated results by the enthalpy method.

Analysis of Non-Fourier Conduction-Radiation Heat Transfer in a Cylindrical Enclosure
Numerical Heat Transfer, Part A: Applications, 2010This article deals with the analysis of non-Fourier conduction and radiation heat transfer in a participating medium contained between 1-D concentric cylinders. The conducting-radiating medium is radiatively absorbing, emitting, and scattering. The non-Fourier effect is analyzed by suddenly perturbing the temperatures of the concentric cylinders.

Comparison of fourier and non-fourier heat transfer in nanoscale semiconductor structures
2014 Semiconductor Thermal Measurement and Management Symposium (SEMI-THERM), 2014This paper is devoted to the demonstration of fundamental differences between the Fourier and non-Fourier heat transfer mechanisms in nanoscale silicon structures. One-dimensional parabolic and hyperbolic heat equation is solved for a simple test structure. Then, the obtained solutions in frequency and time domains are compared.

Meshless analysis of casting process considering non-Fourier heat transfer
2016Casting is considered as a major manufacturing process. Thermal analysis of a solidifying medium is of great importance for appropriate design of casting processes. The conventional governing equation of a solidifying medium is based on the Fourier heat conduction law, which does not account for the phase-lag between the heat flux and the temperature ...

Numerical solution of non-Fourier heat transfer during laser irradiation on tooth layers
Journal of Mechanical Science and Technology, 2017This study reports on the simulation of temperature distribution of human tooth under a laser beam based on non-Fourier models. The temperature in the tooth depth that directly results from the conduction heat transfer process is caused by the lengthy thermal relaxation time in the tooth layers.

The Analysis of Non-Fourier Heat Transfer Mechanism on Thermal Conductivity for Nanofluids
ASME/JSME 2007 Thermal Engineering Heat Transfer Summer Conference, Volume 1, 2007The paper features the mathematical model representing the analytical calculation of thermal conductivity for nanofluids. The mathematical model was developed on the basis of statistical nano-mechanics. We have made the detailed analysis of the influence of temperature dependence on thermal conductivity for nanofluids.

Size-dependent thermal conductivity in nanosystems based on non-Fourier heat transfer
Applied Physics Letters, 2012Based on a phonon hydrodynamic equation, we derive an analytical model to predict the effective thermal conductivity along dielectric thin films or nanowires with smooth wall surface. The model contains only two parameters: bulk thermal conductivity and Knudsen number, no other fitting parameter included.

International Journal of Thermophysics, 2012
This paper numerically investigates the hyperbolic thermoelastic problem of an annular fin. The ambient convection heat transfer coefficient of the fin is assumed to be spatially varying. The major difficulty in dealing with such problems is the suppression of numerical oscillations in the vicinity of a jump discontinuity. An efficient numerical scheme
