【摘要】 采用目标网状法设计了雾滴荷质比的测定装置,测量了环形电极下双流体荷电喷雾感应荷电雾滴的荷质比,实验表明雾滴荷质比与液体的雾化效果有关。根据感应荷电的圆筒形模型建立了感应荷电雾滴荷质比的计算模型,针对不同粒径的雾滴进行了荷质比的计算,并与实验结果进行了对比。模型计算表明:对于感应荷电雾滴的荷质比在10^-3-10^-4C/kg之间,与实验结果符合较好,并且都是随着荷电电压的增大而增加,随着雾化状况的改善而变大,说明该模型能够在一定程度上对雾滴荷质比的大小进行估算,同时也证明该装置能够较准确地测量雾滴的荷质比。更多还原

【Abstract】 A device of charge to mass ratio for droplets is produced based on the mesh target.The droplets produced by the twin-fluid charged spray for charge to mass ratio is measured under ring electrode.The data show that droplets for charge to mass ratio is relate to the atomization of the fluid.The computation model of induce charging charge to mass ratio for droplets is found based on the cylinder model.The charge to mass ratio for droplets is computed under the different droplets diameters and contrasted with the experiment data.The model computation results indicate that charge to mass ratio is 10^-3—10^-4C/kg and accord with experiment data. The charge to mass ratio is accretion with the high voltage and improving of the fluid.So,the model could estimate the charge to mass ratio for droplets a certain extent.And at the same time the device could measure the charge to mass ratio by rule and line.更多还原
