The wall film ratio is affected by mass proportion of evaporation and splashing. Impingement momentum is major impact factor when varying pressure or distance. Impingement flow mass is major impact factor when varying the impingement angle. Fuel properties (surface tension) are major impact factor when varying blending ratio. The relationships between wall film ratio and Weber number have been given.
