摘要

滴径分布是描述喷嘴雾化性能的一个重要指标.从液滴分裂的自相似性出发，提出了描述气流式雾化过程的液滴有限随机分裂模型.实验和模拟计算结果表明，该模型能较好地模拟三通道喷嘴气流式雾化过程的平均滴径和滴径分布的非线性关系.

Abstract

Droplet size distribution is an important parameter of atomization process.The finite stochastic breakup model of air-blast atomization process with four parameters:initial droplet diameter

diameter of maximum stable droplet

minimum mass ratio of a sub-droplet to the mother droplet and droplet breakup probability is presented according to the self-similarity of droplet breakup.The simulation results of droplet size distribution with this model agreed well with the experimental results of a three-channel nozzle with air and water

obtained by Malvern Laser Particle Sizer Type 3600 measurement.With this model

the nonlinear relationship between average droplet diameters and droplet size distribution of the airblast atomization process could be predicted satisfactorily.
