A plausible approach to heat transfer enhancement: non-Fourier heat transfer in fluids under oscillating conditions

Journal of Physics Communications, 2018
Efficient and optimal energy transport is one of the present challenges in the physics of many different devices. In this context, the dynamic effective thermal diffusivity of a fluid with a non-Fourier heat conduction law is examined. Considering the simplest description for heat conduction beyond Fourier's law (the Cattaneo-Vernotte equation), an ...

Multigrid waveform relaxation for the time-fractional heat equation [PDF]

, 2017
In this work, we propose an efficient and robust multigrid method for solving the time-fractional heat equation. Due to the nonlocal property of fractional differential operators, numerical methods usually generate systems of equations for which the ...
