combustion and injection modelling - Opis:
- In recent years modelling has been applied to investigation of mixture formation, fluid flow, combustion process and pollutant formation in diesel engines. In this study numerical simulation was carried out to investigate the effect of fuel spray characteristics in marine medium speed diesel engine - Sulzer 6A20/24D. 1-D and 3-D CFD fuel spray model was adopted for simulation of atomization and combustion process. For comparison purposes modelling outcome was set against experimental tests results. Operational validation of injection assembly model was performed according to standard marine engine test cycles. Injection pressure history for full load range of the engine has been experimentally established. Fuel oil supply system, test engine cylinder experimental setup, 1-D engine fuel injection assembly model and geometry of cam profile, measured nominal injection duration, comparison of calculated and measured injection pressures, calculated nominal injection process components shape, the cross section of velocity flow field for nominal injection phase and for nominal injection phase, the cross sections of velocity flow field in hole channel for nominal injection phase after cut-off and for nominal injection phase after cut-of, the cavitation-induced spray formation process in modelled combustion chamber are presented in the paper.
