Numerical modeling of combustion in gas engines with prechamber ignition [PDF]

open access: yesInternational Journal of Engine Research
A numerical model is developed to predict the combustion processes in large-bore gas engines featuring prechamber ignition systems and being coupled with Computational Fluid Dynamics (CFD). The proposed combustion model is based on the simultaneous modeling of premixed and partially-premixed flames by an extended progress variable approach.
