Abstract: Combustion efficiency and emission levels are prime concern for the compression ignition engines, which should have high combustion efficiency and meet the stringent emission norms. Combustion is very complex phenomenon which cannot be analyzed easily with the analytical method or different visualization technique. Computational Fluid Dynamics (CFD) has becoming useful tool in understanding the fluid dynamics of IC Engines for design purposes. The methodology for CFD analysis involves use of CATIA V5 for geometry creation. ANSYS FLUENT is used as solver. CFD analysis is able to predict in cylinder combustion, peak pressure and peak temperature hence proposed combustion model can be utilizes for combustion analysis.
Keywords: Computational Fluid Dynamics, CI engine, Combustion modeling.
