Abstract

Blended fuels have great potential for substitution with petroleum fuel for the purpose of emission control and fuel efficiency improvement. This research is to investigate the effect of high injection pressure and high ambient condition of biodiesel blends on spray characteristics using Computational Fluid Dynamics (CFD). The variables in this study are the various injection pressure (220, 250 and 280 MPa) and ambient temperatures (850, 950, and 1050 K), while the ambient pressure is kept constant at 8 MPa. The simulation in ANSYS FLUENT was used to observe the spray characteristics of biodiesel blends at various conditions. Simulation results show that longer spray penetration length with smaller spray significantly affects the mixture formation biodiesel blends compared to pure diesel at high injection pressure and ambient temperature.
