Slags as Thermal Energy Storage Media for Concentrated Solar Power and Renewable Energy Integration

Energy Storage, Volume 7, Issue 8, December 2025.
ABSTRACT The growing demand for low‐cost, high‐performance thermal energy storage (TES) materials has prompted interest in repurposing metallurgical slags in concentrated solar power (CSP) systems. This review critically evaluates the potential of various steel, copper, and aluminum slags as high‐temperature TES media in packed‐bed configurations ...

Investigation on heat extraction characteristics in randomly fractured geothermal reservoirs considering thermo‐poroelastic effects

Energy Science &Engineering, Volume 7, Issue 5, Page 1705-1726, October 2019., 2019
This paper develops a fully coupled THM model to investigate the thermo‐poroelastic responses during heat extraction in randomly fractured geothermal reservoirs. The effect of different fracture network morphology on the heat extraction performance is revealed.

Analysis of thermal performance and irreversibility of double-diffusive buoyancy-driven nano-suspension subject to local thermal non-equilibrium model

Case Studies in Thermal Engineering
In fact, local thermal equilibrium (LTE) would be unsuitable when it comes to nuclear reactors, electronic equipment, space devices, geothermal engineering, and high-conductivity foams, due to prominent temperature discrepancy between the two ...

Effects of Local Thermal Nonequilibrium and Sediment Heterogeneity on Heat Tracer‐Based Downwelling Flux Quantification in Streambeds

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Local thermal nonequilibrium (LTNE) effects in heterogeneous media can affect subsurface temperature distributions, as well as the capacity of the heat transport model to solve the inverse problem of estimating groundwater fluxes. We present a synthetic coupled flow and heat transport numerical model with five scenarios to analyze the ...

Exact Analytical Nanofluid Flow and Heat Transfer Involving Asymmetric Wall Heat Fluxes with Nonlinear Velocity Slip

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
Nanofluid slip flow and heat transfer over the microchannel with asymmetric wall heat fluxes are investigated theoretically. The local thermal nonequilibrium model in which there is a difference between the solid temperature and nanofluid temperature is modified by considering the nonlinear velocity slip and temperature jump. Exact analytical solutions

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

On Radial Heat Transport in Porous Aquifers With Nonlinear Velocity‐Dependent Thermal Dispersion

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract Accurate modeling of heat transport behavior near the test well is essential for the efficient operation and management of aquifer thermal energy storage (ATES) systems. Existing models typically assume a linear relationship between thermal dispersion and velocity, whereas previous controlled experiments have revealed that this relationship is

Role of two isothermal cylinders towards three-dimensional flow and melting of phase-change materials

Case Studies in Thermal Engineering
Recently, investigators focused on examining the melting of phase change materials (PCM) in regular two-dimensional or three-dimensional flow domains. At the same time, this topic still needs more study to get a better understanding of it.

Effects of Alumina–Tantalum Hybrid Nanofragment on Engine Oil Flow Using a New Local Thermal Nonequilibrium Formulation

Complexity, Volume 2025, Issue 1, 2025.
The aim of this work is to study the alumina–tantalum/motor oil hybrid nanoliquid flow in a porous cavity subjected to a uniform magnetic field. We have used the Darcy–Bénard convection model for the momentum equation and a new local thermal nonequilibrium formulation for heat transport.
