Modelling Bidispersive Local Thermal Non-Equilibrium Flow

Fluids, 2017
In this work, we present a system of equations which describes non-isothermal flow in a bidispersive porous medium under conditions of local thermal non-equilibrium.

Influence of local thermal non-equilibrium on enhanced geothermal system

Shenzhen Daxue xuebao. Ligong ban, 2022
Effective development of hot dry rock depends on complex fracture network formed by the enhanced geothermal system. Different scales of mass and heat transfer environment are formed between tight matrix and different fractures, which leads to the ...

Developing generalized model representations of thermal shock for local non-equilibrium heat transfer processes

Российский технологический журнал, 2023
Objectives. Processes of energy transfer in solids and resultant thermal loads are widespread in nature and technology. This explains the scientific and practical significance of constructing a theory of these processes, as well as developing effective ...

Numerical analysis of hybrid nanofluid natural convection in a wavy walled porous enclosure: Local thermal non-equilibrium model

International Journal of Thermofluids, 2022
A numerical study of the Buoyancy-driven flow in a porous enclosure, having a bottom heated wavy wall, filled with Cu-Al2O3/water hybrid nanofluid is performed using the local thermal non-equilibrium model.

A local thermal non-equilibrium model for rain-on-snow events [PDF]

Hydrology and Earth System Sciences
Liquid-water movement through a snowpack, e.g., during rain-on-snow events or meltwater infiltration, is an essential process to understand runoff generation, flash floods, and snow avalanches.

Flow and Convection in Metal Foams: A Survey and New CFD Results

Fluids, 2020
Metal foams are widely studied as possible tools for the enhancement of heat transfer from hot bodies. The basic idea is that a metal foam tends to significantly increase the heat exchange area between the hot solid body and the external cooling fluid ...

Free convection of a suspension containing nano-encapsulated phase change material in a porous cavity; local thermal non-equilibrium model

Heliyon, 2020
Due to the instinctive temperature-dependent heat capacity of the Nano-Encapsulated Phase Change Material (NEPCM), there is a growing interest in the potential applications of such materials in heat transfer. As such, steady-state natural convection in a

Non-equilibrium steady states in quantum critical systems with Lifshitz scaling

Journal of High Energy Physics, 2019
We study out-of-equilibrium energy transport in a quantum critical fluid with Lifshitz scaling symmetry following a local quench between two semi-infinite fluid reservoirs.

Magnetohydrodynamic mixed convection of TiO2–Cu/water between the double lid-driven cavity and a central heat source surrounding by a wavy tilted domain of porous medium under local thermal non-equilibrium

SN Applied Sciences, 2023
Article Highlights The flow shear at the proposed model is more feasible for the heat and mass transfer than the buoyancy force. Local thermal non-equilibrium case creates inaccessible regions that disapprove the harmony in the flow behavior.

Impact of local thermal non-equilibrium on temporal thermo-hydro-mechanical processes in low permeable porous media [PDF]

E3S Web of Conferences, 2020
The thermo-hydraulic-mechanical (THM) response of low permeable media is of crucial significance in thermal fracturing for production of unconventional shale oil, enhanced geothermal systems, and waste disposal.
