Characterizing the Atomization of a Liquid Mass

Canada’s commitment to Paris accord can only be realized with a significant reduction in emissions from oil and gas, and transportation sectors. Oil and gas accounts for 26% and transportation for 23% of Canada’s total GHG emissions. In North America, combustion of gasoline and diesel fuel make up for 84% of all transportation energy. Therefore, any improvement in combustion energy efficiency, can have a large impact on the total emission. Combustion efficiency and emission intimately relate to the fuel injection and mixing inside the combustion chamber. More and more engines utilize Gasoline Direct Injection (GDI) because of its higher fuel efficiency. In addition, diesel and biodiesel fuels are become more popular, again because of their fuel efficiency. Therefore, further improvements in the fuel efficiency and emission reduction require a better understanding of the fuel injection and atomization processes and development of models to predict these processes. Such models can be implemented in spray combustion codes to modify engine designs, optimize the combustion efficiency, and reduce emissions.
