    • 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 ...

    • Comprehensive Char Particle Gasification Model Adequate for Entrained-Flow and Fluidized-Bed Gasifiers 

      Tilghman, Matthew B.; Haugen, Nils Erland L; Mitchell, Reginald E. (Journal article; Peer reviewed, 2017)
      A robust, single-particle gasification model is presented that is capable of predicting char particle behavior in environments established in typical fluidized bed and entrained flow gasifiers. It employs a heterogeneous ...

    • 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 ...

    • The conversion mode of a porous carbon particle during oxidation and gasification 

      Haugen, Nils Erland Leinebø; Tilghman, Matthew B.; Mitchell, Reginald E. (Journal article; Peer reviewed, 2014)
      Studies have shown that both char particle diameter and apparent density vary during char conversion at high temperatures. To account for such variations, power-law expressions have been used to correlate r p /r p,0 and ρ ...
