In this work, two numerical approaches, namely particle-resolved simulations (3D PRS) and
porous media model (PMM), are assessed using a 2D axisymmetric CFD pseudo-state …

Abstract scCO 2 (supercritical CO 2) is now an efficient, clean, and pollution-free solvent
widely used in industrial productions, such as extraction, printing and dyeing, as well as …

This work is devoted to the three-dimensional numerical investigation of a chemical reacting
porous carbon particle moving in a hot O 2/CO 2 gas. The porous particle was represented …

The aim of this work is to study spatially and chemically resolved particle combustion cases
to understand chemical and laminar transport processes and to support model development …

The final carbon conversion rate is of critical importance in the efficiency of gasifiers.
Therefore, comprehensive modeling of char particle conversion is of primary interest for …

Based on pseudo-steady-state approach, the effect of particle size and porosity on
conversion characteristics of single coal char particle moving in high temperature O 2/CO 2 …

The change in a particle's morphology affects both its trajectory and its carbon consumption
rate. For that reason, the present work studies the evolution of particle's morphology during …
