多毛细管稳定喷洒电雾化特征研究(一)--实验设备设计及粒径测量方法

Numerical simulation and experimental study were carried out for the device of multi-capillary electrical atomization spray. According to the numerical analysis results of electrical atomization formed by linearly arranged capillary arrays and corresponding electrostatic field, the influence of electric field intensity distribution on the stable atomization was preliminarily analyzed. Based on above results, an optimized design was proposed, which could be further applied to multiple-lines arrays. Through these arrangements, stable multi-capillary electrical atomization spray is realized, and stable and reproducible spray could be achieved easily. Electrical atomization sprayed droplets were collected on a piece of oil covered glass, and then were analyzed with microscope-camera system. Image processing results show that the particle size distribution has good mono-dispersion. This is according with electrical atomization spray.
