Extending stochastic soot simulation to higher pressures
The purpose of this communication is to extend the applicability of the work reported by M. Balthasar and M. Kraft in Combustion and Flame 133 (2003) pp. 289-298 to higher pressure flames. The original work was only applied to atmospheric-pressure flames in which the Knudsen number of the soot particles satisfied Kn > 10. The physical model for coagulation at lower Knudsen numbers is taken from other literature and the implementation relies on a new generalization of the concept of majorant kernel which is presented here. Fortran 90 source code implementing the newly extended simulation is freely available for download.
