摘要

研究了混合液压力、固体质量分数、固体微粒直径、微粒密度对雾滴的体积-表面积直径（d32）的影响.在实验中采用三维激光相位多普勒LDV/APV测试系统测定了最大概率分布的雾滴直径（d32），使用高速摄像仪记录了雾化的过程.研究发现混合液的压力和固体微粒密度对雾滴直径（d32）的影响呈非单调性，雾滴直径（d32）随其增大先减小、再增加；而雾滴直径随固体微粒的直径、混合液固体质量分数的增加而增大.实验结果与数学模型能较好地吻合，可为工业性设计提供理论依据.

Abstract

In the process of spraying of liquid-solid suspension

there are many factors that affect the diameter (d32) of spray droplet of the suspension

such as suspension pressure

solid content and diameter and density of mini-particle. The diameter of maximum probability distribution of the spray droplet of suspension was measured with the system of 3D LDV/APV and the process of spraying was recorded with the FASTCAM-Super in situ measurement.The relationship of d32 with the suspension pressure and mini-particle density is non-monotonic

with d32 decreasing then increasing with suspension pressure and mini-particle density

while the d32 is increasing monotonously with mini-particles diameter and solid content in suspension. The experiment matched well with the mathematical model in the previous.
