Non-Fourier heat conduction in oil-in-water emulsions [PDF]

International Journal of Heat and Mass Transfer, 2019
Abstract Emulsions have widely been used in various application, e.g. in energy system as a potential second refrigerant. However, there is a lack of comprehensive study on extraordinary effective thermal conductivity enhancement in the oil-in-water (O/W) emulsions, and effects of temperature and droplet size were not considered in the widely used ...

Non-Fourier Heat Conduction in Carbon Nanotubes [PDF]

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 ...

A peridynamic framework and simulation of non-Fourier and nonlocal heat conduction

International Journal of Heat and Mass Transfer, 2018
Abstract Non-Fourier and nonlocal heat conduction phenomena have been observed in many cases in modern industry. They have been modeled by differential equations with phase lags or by Fourier-type integral formulation. This paper presents a peridynamic non-Fourier heat conduction model to consider the non-Fourier and nonlocal effects simultaneously ...

Non-Fourier heat conduction in a hollow sphere with periodic surface heat flux

International Communications in Heat and Mass Transfer, 2009
Presented is the analysis of non-Fourier effect in a hollow sphere exposed to a periodic boundary heat flux. The problem is studied by deriving an analytical solution of the hyperbolic heat conduction equation. Using the obtained analytical expression, the temperature profiles at outer and inner surfaces of the sphere are evaluated for various thermal ...
