Abstract
We describe the differences in the combustion behavior within a model opposed-flow solid fuel burner produced by three different chemical reaction models: a two-step global mechanism, a six-step global mechanism, and a pressure-comprehensive skeletal model, all of which assume butadiene as the primary fuel source. Details of the implementation of these models in conjunction with an equilibrium interfacial pyrolysis model for the solid gas phase change process are provided. Of particular interest are the differences in flame structure and dynamics predicted by each reaction model in comparison to the performance benefits gained by model simplifications. We provide some observations regarding the use of these global reaction models in a purely non-premixed combustion setting. A preliminary flamelet generated manifold is presented to be explored in future work.
