Combustion theory and modeling [PDF]

open access: yesProceedings of the Combustion Institute, 2005
In honor of the fiftieth anniversary of the Combustion Institute, we are asked to assess accomplishments of theory in combustion over the past fifty years and prospects for the future. The title of our article is chosen to emphasize that development of theory necessarily goes hand-in-hand with specification of a model.

Group Combustion of Dispersed Spherical Core–Shell Nanothermite Particles

open access: yesThermo, 2022
The group combustion characteristics of core–shell nanothermite particles differ from other dispersed solid or liquid fuels. In a core–shell structure, each discrete nanothermite particle can undergo an exothermic reaction as the oxygen atoms in the ...

Numerical analysis of pulverized biomass combustion [PDF]

open access: yesE3S Web of Conferences, 2021
Combustion of pulverized biomass in a laboratory swirl burner is computationally investigated. The two-phase flow is modelled by an Eulerian-Lagrangian approach. The particle size distribution and turbulent particle dispersion are considered.
