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 (d3 2 )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 (d3 2 ) ,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 (d3 2 )的影响呈非单调性 ,雾滴直径 (d3 2 )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 .
In the process of spraying of liquid solid suspension, there are many factors that affect the diameter ( d 32 ) 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 d 32 with the suspension pressure and mini particle density is non monotonic,with d 32 decreasing then increasing with suspension pressure and mini particle density, while the d 32 is increasing monotonously with mini particles diameter and solid content in suspension The experiment matched well with the mathematical model in the previous.
