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.
