Local Non‐Equilibrium Thermal Effects in Solid Oxide Fuel Cells with Various Fuels

Energy Technology, 2012
AbstractLocal thermal equilibrium (LTE) is a common assumption used in thermal modeling of solid oxide fuel cells (SOFCs). However, its validity has not been fully verified. To examine the validity of the LTE assumption, a thermal model has been developed to evaluate the local thermal non‐equilibrium effect of SOFC electrodes with various fuels ...

Heat Transfer Using the Local Thermal Non-Equilibrium Model

2012
For an impinging jet, the flow is considered to be turbulent for \( Re > 1,000 \), where the Reynolds number is given by \( Re = \frac{{\rho \,v_{0} \,D_{h} }}{\mu } \), where \( v_{0} \) is the incoming jet velocity and \( D_{h} = B \) when calculating Re for adequate comparisons with similar simulations in the literature (see Fig. 1.2).

Modeling and Simulation of Local Thermal Non-equilibrium Effects in Porous Media with Small Thermal Conductivity

Transport in Porous Media, 2018
The two-equation model in porous media can describe the local thermal non-equilibrium (LTNE) effects between fluid and solid at REV scale, with the temperature differences in a solid particle neglected. A multi-scale model has been proposed in this study.

The linear stability of a developing thermal front in a porous medium: The effect of local thermal non-equilibrium

International Journal of Heat and Mass Transfer, 2007
In this paper we analyze the stability of the developing thermal boundary layer which is induced by a step-change in the temperature of the lower horizontal boundary of a uniformly cold semi-infinite porous medium. Particular attention is paid to the influence of local thermal non-equilibrium between the fluid and solid phases and how this alters the ...

Forced convection in porous microchannels with viscous dissipation in local thermal non-equilibrium conditions

International Communications in Heat and Mass Transfer, 2016
Abstract Fully developed, steady-state forced convection, in parallel-plate microchannels, filled with a porous medium saturated with rarefied gases at high temperatures, in local thermal non-equilibrium (LTNE) condition, is investigated for the first-order slip-flow regime (0 ≤ Kn ≤ 0.1).

The role of local thermal non-equilibrium in modelling smouldering combustion of organic liquids

Proceedings of the Combustion Institute, 2019
Abstract A one-dimensional numerical model of smouldering combustion was developed in order to better understand smouldering and accurately predict forced, upwards, self-sustained smouldering for the purposes of treating hydrocarbon-contaminated soil.

Research on local thermal non-equilibrium boundary of crushed rock embankment

Due to its excellent thermal protection effect, crushed rock are widely used in embankment engineering in permafrost regions. Accurately describing the heat transfer mechanism on the surface of crushed rock plays an important role in predicting the long-term service performance of crushed rock embankments.
