- Summary:
- Flash boiling, as a potential way to achieve good atomization at low cost, is of great interest to researchers. A customized wide-angle multi-hole gasoline injector was utilized in this work to see how commercial E10 gasoline spray behaves at high injection pressure of gasoline compression ignition (GCI) application from 5 MPa to 45 MPa, and ambient gas pressure from 3 kPa to 300 kPa . A diffused back illumination technique was implemented to visualize the spray at flash boiling and non-flashing conditions. Three different types of spray pattern were observed and correlated to the characteristics like penetration length and spray width. A new parameter, namely optical thickness, was applied in the field of characterizing flash boiling effect for the first time, and compared with widely used penetration length and spray width. Optical thickness was found to be a good indicator for collapse, transition, and non-flashing spray
