The effect of local thermal non-equilibrium on impulsive conduction in porous media

International Journal of Heat and Mass Transfer, 2007
We examine the effect of local thermal non-equilibrium on the evolution of the stagnant temperature field in a semi-infinite porous medium. When local thermal equilibrium pertains, the temperature field which is induced by a step change in the temperature of a plane boundary is given by the classical conduction solution involving the complementary ...

Analytical considerations of local thermal non-equilibrium conditions for thermal transport in metal foams

International Journal of Thermal Sciences, 2015
Abstract As a new-type extending surface, metal foam owns great potential in next generation heat transfer technologies. Convective heat transfer performance in metal foams is numerically investigated based on the local thermal equilibrium (LTE) model and the local thermal non-equilibrium (LTNE) model.

Analysis of thermally developing flow in porous media under local thermal non-equilibrium conditions

International Journal of Heat and Mass Transfer, 2013
Abstract In the present study, analytical solutions for thermally developing flows in porous media under local thermal non-equilibrium (LTNE) condition are derived for different fundamental models. The analytical solutions are validated by comparison with the numerical results.

Transient thermoporoelastic model under local thermal non-equilibrium

Geomechanics for Energy and the Environment, 2019
Abstract Wellbore stability is a key challenge for oil and gas industry since it adds a great deal of additional cost to the industry. Traditional wellbore stability models such as elastic and poroelastic models may not produce reliable stress field around a wellbore since they consider isothermal wellbore condition.

Stability of penetrative convective currents in local thermal non-equilibrium

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences
The aim of this paper is to investigate the onset of penetrative convection in a Darcy–Brinkman porous medium under the hypothesis of local thermal non-equilibrium. For the problem at stake, the strong form of the principle of exchange of stabilities has been proved, i.e.

Thermoporoelastic wellbore stability model with local thermal non-equilibrium

2018
Wellbore stability is a key challenge for the exploration and production industry since it adds a great deal of additional cost. Traditional wellbore stability models such as elastic and poroelastic models are not sufficient in modeling the stability and produce erroneous results since they consider an isothermal condition.
