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.

Starting flow in an impulse wind tunnel with a throttled prechamber

open access: yesJournal of Physics: Conference Series, 2019
Abstract The unsteady axisymmetric flow forming in the process of starting an impulse wind tunnel equipped with a throttled prechamber was numerically simulated. A regime with the operating flow Mach number M = 8 was under consideration. Numerical simulation on the basis of Reynolds-averaged Navier–Stokes code and the k-ω SST turbulence ...
