Abstract
A corresponding physical model which is close to reality was established according to the motion characteristics of oil droplet formed from primary fuel atomization.Intrinsic relation of each parameter can be derived through N-S equation and linearization analysis method.Based on the solutions, the effects of Ma number, Bond number, Oh number and gas-liquid density ratio k secondary breakup of oil droplet were studied respectively. Analysis results show that gas compressibility does promote secondary breakup of oil droplet but the compact is not obvious.So in general, influence of gas compressibility can be neglected.In addition, the viscosity of oil drop can inhibit breakage and the acceleration is a direct cause of secondary breakup.Therefore, increasing Bond number is meaningful to the quality of atomization.
