Flow Analysis of IC Engines
Vehicles with SI engines are provided with carburettor for fuel air mixture supply. Fuel consumption affects the design of carburettor. For better uniform fuel air supply there is a need to design the carburettor with an effective design tool. Parameters of the carburettor will be analysed using computational fluid dynamics. The results obtained from the open source software's enGrid, open FOAM, will be analysed for optimum design of a carburettor. Current CFD models describe important physical and chemical processes of engine flows, but validation experiments are needed for model development and improvement. CFD combustion models capture engine performance and emissions trends and can be combined with optimization tools for design and evaluation of engine design concepts. In recent years CFD has been successfully established for the calculation of fluid flow, mixture formation and combustion in internal combustion engines as a complementary tool to in-cylinder pressure analysis and optical mixture formation and combustion diagnostics.
