The effect of local thermal non-equilibrium on the onset of thermal instability for a metallic foam [PDF]

open access: yesPhysics of Fluids, 2022
Mixed convection in metallic foams modeled with Darcy's law under local thermal non-equilibrium conditions is investigated, where the solid phase thermal conductivity is assumed to be infinitely larger than its fluid phase counterpart. A linear and modal stability analysis was employed to evaluate the convective and absolute instability thresholds as ...

An Analysis of Thermal Radiation in Porous Media Under Local Thermal Non-equilibrium [PDF]

open access: yesTransport in Porous Media, 2020
The present work investigates the thermal radiation transport inside porous media under local thermal non-equilibrium conditions. Two different geometrical situations, a two-dimensional channel and a cylindrical geometry, are considered in the analysis.

Thermal recovery from a fractured medium in local thermal non‐equilibrium [PDF]

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, 2012
SUMMARYThermal recovery from a hot dry rock (HDR) reservoir viewed as a deformable fractured medium is investigated with a focus on the assumption of local thermal non‐equilibrium (LTNE).Hydraulic diffusion, thermal diffusion, forced convection and deformation are considered in a two‐phase framework, the solid phase being made by impermeable solid ...

Uniqueness and decay in local thermal non‐equilibrium double porosity thermoelasticity [PDF]

open access: yesMathematical Methods in the Applied Sciences, 2018
This paper studies a model for thermoelasticity where the body has a double porosity structure. There are the usual pores associated to a porous body, herein called macro pores. In addition, the solid skeleton contains cracks or fissures that give rise to a micro porosity. The fully anisotropic situation is analyzed.

Effects of thermal properties of porous media on local thermal (non-)equilibrium heat transport

open access: yesJournal of Groundwater Hydrology, 2023
When analyzing convective heat transport, local thermal equilibrium (LTE) between the solid and fluid phases of water-saturated porous media is commonly assumed. However, experiments investigating the scope of validity of this assumption are lacking. We conducted heat transport experiments using two types of porous media having the same grain size (5 ...

Thermal instability of a nanofluid layer under local thermal non-equilibrium

open access: yesNano Convergence, 2015
In this paper, we study the effect of local thermal non-equilibrium on the linear thermal instability in a horizontal layer of a Newtonian nanofluid. The nanofluid layer incorporates the effect of Brownian motion along with thermophoresis. A two-temperature model has been used for the effect of local thermal non-equilibrium among the particle and fluid

Thermal behavior of Composite Material (nanoPCM/aluminum foam) used for thermal energy storage (TES) applications

open access: yesComptes Rendus. Physique, 2020
Thermal energy storage systems (TESS) using phase change materials (PCM) have attracted interest in various fields of science and technology. However, the interest of these systems is limited by the relatively low thermal conductivity of PCMs and their ...

Thermal convection for a Darcy-Brinkman rotating anisotropic porous layer in local thermal non-equilibrium [PDF]

open access: yesRicerche di Matematica, 2021
AbstractThe onset of natural convection in a fluid-saturated anisotropic porous layer, which rotates about the vertical axis, under the hypothesis of local thermal non-equilibrium, is analysed. Since the porosity of the medium is assumed to be high, the more suitable Darcy-Brinkman model is adopted.
