A comprehensive model for char particle conversion in environments containing O2 and CO2
Haugen, Nils Erland L; Mitchell, Reginald E.; Tilghman, Matthew B. (Journal article; Peer reviewed, 2015)In this work, conversion of char is studied in a simulation code that includes a simplified heterogeneous adsorption–desorption reaction mechanism for char chemical reactivity and uses GRI-Mech 3.0 as the chemical kinetic ... -
Modeling radiation in particle clouds: on the importance of inter-particle radiation for pulverized solid fuel combustion
Haugen, Nils Erland L; Mitchell, Reginald E. (Journal article; Peer reviewed, 2014)The importance of inter-particle radiation for clusters of gray and diffuse particles is investigated. The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a ... -
Numerical approaches for thermochemical conversion of char
Haugen, Nils Erland L; Loong, Brandon Ka Yan; Mitchell, Reginald E. (Peer reviewed; Journal article, 2022)This paper gives a review of the current state of the art for numerical simulations of char conversion. In particular, it presents models that have been developed to describe the physical and chemical phenomena that ...
