Abstract:
A numerical model is developed for the prediction of unburned hydrocarbons (UHC) emissions in gas engines. Local UHC sources in the engine combustion chamber are simulated and the unburned fuel leaving the engine is calculated and compared with experimental data from a single cylinder research engine for different operating conditions. The calculation procedure is applicable for complex three dimensional geometries and regards the local flow and turbulence conditions. A hybrid model is proposed...     »
