Analysis Of Droplet Deformation And Charge Transfer Characteristics Based On Machine Vision

The blade-less wind power generation system atomizes the liquid medium through an induction-charged atomizer.Under the action of wind,the atomized charged droplets move in the opposite direction of the electric field force,thus increasing the whole electric potential energy of the system,to convert wind energy into electricity.The analysis of the droplet charge mechanism and the charge transfer characteristics can provide a reference for the optimization of the parameters of the atomization system,so as to increase the total electric potential energy and the energy efficiency of the system.In this paper,the variation of droplet shape and the distribution of surface charge under the action of electrostatic field are studied by theoretical analysis and experimental comparison,the change of droplet shape and the characteristics of charge transfer in drop-like,spindle and jet modes are studied.The results show that the electric field force affects the rate of charge transfer and the deformation of Droplet The influence of the structure of electrode-nozzle and the characteristics of atomizing medium on the deformation of droplets is established.The area,perimeter and deformation degree of droplets with different shapes are analyzed by means of the target size tracking algorithm,gravity and surface tension play a leading role in the droplet morphology change.With the increase of applied voltage,the electric field force gradually becomes the main factor affecting the droplet morphology change The relation curves of electrode voltage,electrode shape,dielectric properties,nozzle structure and droplet charge were obtained.It is found that the droplet charge is mainly affected by the droplet charge density,the droplet surface area and the droplet detachment rate The results show that the electric charge of the droplet is affected by the area of the electric double layer between the metal nozzle and the atomizing medium,and the inner diameter of the nozzle affects the thickness of the diffusion layer and the size and distribution of the atomized droplet,but it has no obvious effect on the droplet charge.
