Outline of Final Research Achievements

Due to the harmful influence of fine particles on human heath, the particulate mass and number regulations are included in the European emission standards for passenger cars, indicating that further understanding of soot particle formation under high pressure conditions and construction of a prediction model are required. In this study, measurements of the particle volume fraction and soot pre-cursors were carried out for counter flow non-premixed propane flames at elevated pressure. Experimental results were compared with numerical results calculated by using existing soot particle prediction models. As a result, we have obtained development guidelines for a soot prediction model applicable to high pressure conditions.
