Study of component proportion effects on flash boiling atomization with ternary-alkane fuel mixtures

When liquid fuel is injected under superheated conditions, it would experience rapid evaporation in the form of flash boiling. Bubbles constantly generated inside can enhance atomization and spray, further changes spray macroscopic structure. Former studies have shown that presence high volatility significantly prompt low fuel. However, effects component proportion on boiling multi-component not been fully understood yet. Moreover, lack an appropriate index for hinders deeper physical insight into their behavior. To bridge these gaps, three single-component alkanes (n-pentane, iso-octane, n-decane) with noticeably various vapor pressures were blended different mixtures to investigate influence Their cross-patterns tested temperature ambient pressure using a high-speed planar laser Mie-scattering imaging system. The difference was analyzed. results indicated light-end (with highest pressure) dominates behavior due its likelihood evaporation. Based results, new modified from ratio bubble point proposed predict This newly found better elucidate test fuels.
