Abstract: Abstract Transient combustion behavior of char particle arrays in oxy-fuel atmosphere is analyzed with a resolved-particle two-dimensional simulation framework, considering both heterogenous and homogeneous chemical reactions. A range of various parameters is considered, such as… read more here.

DOI: 10.1016/j.fuel.2020.119615
Abstract: Abstract Our previous particle-resolved simulation study has elucidated that the conversion of coal char particle at analogous chemical looping with oxygen uncoupling conditions (a relatively low temperature, e.g., 900 °C, and relatively low O2 concentration but… read more here.

DOI: 10.1016/j.fuel.2020.119738
Abstract: Abstract Simulations of unsteady char particle combustion rely on various models that are necessary in order to correctly predict the governing flow and combustion processes. These models, in turn, rely on model parameters, which are… read more here.
