Fractional melting process in inclined containers using (NePCM) and hybrid nanoparticles

open access: yesAlexandria Engineering Journal, 2023
Using substances of high latent heat such as phase change materials is a perfect technique in the energy storage units. Additionally, examining the heat transport and melting process for these materials is beneficial for a wide variety of solar-related ...

Fluctuating surface-current formulation of radiative heat transfer: theory and applications

open access: yes, 2013
We describe a novel fluctuating-surface current formulation of radiative heat transfer between bodies of arbitrary shape that exploits efficient and sophisticated techniques from the surface-integral-equation formulation of classical electromagnetic ...

Effects of Thermal Relaxation on Temperature Elevation in Ex Vivo Tissues During High Intensity Focused Ultrasound

open access: yesIEEE Access, 2020
The introduction of thermal relaxation makes non-Fourier heat transfer more effective than Pennes equation to reflect rapid bio-heat transferring during HIFU, however, the contribution of thermal relaxation in specific tissues needs to be further ...

New asymptotic heat transfer model in thin liquid films

open access: yes, 2017
In this article, we present a model of heat transfer occurring through a li\-quid film flowing down a vertical wall. This new model is formally derived using the method of asymptotic expansions by introducing appropriately chosen dimensionless variables.

Mixed Convection and Thermally Radiative Flow of MHD Williamson Nanofluid with Arrhenius Activation Energy and Cattaneo–Christov Heat-Mass Flux

open access: yesJournal of Mathematics, 2021
In this paper, we explored the impact of thermally radiative MHD flow of Williamson nanofluid over a stretchy plate. The flow in a stretchy plate is saturated via Darcy–Forchheimer relation. Cattaneo–Christov heat-mass flux theory is adopted to frame the

Fourier Heat Conduction as a phenomenon described within the scope of the Second Law

open access: yes, 2014
The historical development of the Carnot cycle necessitated the construction of isothermal and adiabatic pathways within the cycle that were also mechanically "reversible" which lead eventually to the Kelvin-Clausius development of the entropy function ...

Stagnation point flow of third-grade liquid due to variable thickness: A useful application to non-Fourier heat flux approach

open access: yesResults in Physics, 2018
The impact of modified Fourier’s relation in non-linear mixed convective flow of third grade liquid is examined in this article. Stagnation point flow is considered. Variable thermal conductivity and thermal stratification are examined.

Non-Fourier Heat Transfer with Phonons and Electrons in a Circular Thin Layer Surrounding a Hot Nanodevice [PDF]

open access: yesEntropy, 2015
A nonlocal model for heat transfer with phonons and electrons is applied to infer the steady-state radial temperature profile in a circular layer surrounding an inner hot component. Such a profile, following by the numerical solution of the heat equation, predicts that the temperature behaves in an anomalous way, since for radial distances from the ...
