Investigating the effects of split injection with different injection patterns on diesel spray mixing

In recent studies, it has been established that improvements in the injection rate results improved mixing, combustion efficiency, and reduced pollutant emissions. Varying rates have observed to find out optimization rate. this study, split with different was used as flexible investigate diesel spray mixing efficiency. Large eddy simulation (LES) complex processes of unsteady turbulence. The combined fuel approximate ramping-down shape. showed formation a highly unstable aerosol vapor structure turbulence produces vortex area. powerful provide very strong formation. backflow are evident when dwell time is setup. huge influence on efficiency spray. Basic predictions revealed inverse pressure affect structure. Another prediction initial significant impact evaporation even using same quantity condition. double-rectangular slight effect radial extension, area grows rapidly while equivalence ratio low. double-drop high difference great extension length. Additionally, higher lower ratios more efficient mixing.
