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 ...

The transient temperature response of a bimaterial with a circular insulated interface region is studied under sudden heating or cooling. The time-fractional dual-phase-lag heat conduction model is adopted to simulate the non-Fourier effect. The problem is reduced to an initial-boundary value problem.

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.

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.

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

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.
