With increasing the computational resources, the number of publications about coupled
computational fluid dynamics–discrete element method is in the rise in the recent years. This …

Flow, heat, and mass transfer in fixed beds of catalyst particles are complex phenomena
and, when combined with catalytic reactions, are multiscale in both time and space; …

Three Ni-based natural gas steam reforming catalysts, ie, commercial JM25-4Q and JM57-
4Q, and a laboratory-made catalyst (26% Ni on a 5% SiO2–95% Al2O3), are tested in a …

As multiscale structures are inherent in multiphase flows, constitutive models employed in
conjunction with transport equations for momentum, species, and energy are scale …

Among the different thermo-chemical recycling routes for plastic waste valorization,
gasification is one of the most promising, converting plastic waste into syngas (H2+ CO) and …

In this work, we present a rigorous derivation of the volume-filtered viscous compressible
Navier–Stokes equations for disperse two-phase flows. Compared to incompressible flows …

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

Particle resolved direct numerical simulation (PR-DNS) has emerged as a promising method
to improve gas-particle heat transfer closure models. To date, this method has been applied …

Adsorption processes may be classified as purification or bulk separation, depending on the
feed concentration of the compounds to be adsorbed (adsorbates). The adsorption …

We use particle-resolved direct numerical simulation (PR-DNS) as a model-free physics-
based numerical approach to validate particle acceleration modelling in gas-solid …
