Large amounts of high-temperature solid granular (HTSG) materials are produced
throughout the world in metallurgy and building materials industries whose activities are …

Merits in the inherent safety characteristics and multiple applications, cause the pebble‐bed‐
type nuclear reactors, including the High‐Temperature Gas‐cooled Reactors, Fluoride‐salt …

Although interest in redox flow batteries (RFBs) for energy storage has grown over the last
few years, implementation of RFB technology has been slow and challenging. Recent …

Electrochemical reactors are more and more equipped with 3D electrodes such as foams
and felts instead of flat electrodes, because of their large surface area and ability to reduce …

A three dimensional CFD model was developed for studying flow and heat transfer in fixed
beds with cylindrical particles for low tube to particle diameter ratios. The packing structures …

This work presents the design, experimental and numerical results related to a pilot-scale
one-tank (thermocline) thermal energy storage (TES) combining latent and sensible heat …

Fixed bed reactor is widely used in the petrochemical industry. The most rigorous
description of it is particle-resolved simulation. In this study, a particle-resolved CFD model …

This work aims to investigate the effects of particle size on flow regimes and validation of
Darcy law. Experiments were conducted in sand columns with five different particle sizes of …

The effective thermal conductivity (ETC) is a key parameter of the heat transfer models in
high temperature pebble-bed reactors. The ETC in a simple cubic packed bed of graphite …

In the present study, the dimensionless method of Ergun's correlation is used to investigate
the flow regimes and the pressure drop characteristics in the packed beds with non …
