Abstract
Under exciting of high pulse electric field, it was very important to electro- dehydration of emulsified oil that drop happened to being flexing-deforming vibration. So far, it was scarce that people had studied on theoretical calculation of drop’s vibration. Single vibrating drop, in oil, was regarded as the research object under high pulse electric field, and established vibrating dynamics model of drop. By resolving the model, it was obtained that drop’s vibration simple approximate expression and swing-frequency characteristic expression. Results of calculating sample and experiment showed that the method of vibration calculating was reasonable and it was verified that the model, especially forecasting drop’s resonance amplitude and frequency, could efficiently calculate its amplitude. This research would be helpful to making highly efficient electro- dehydration machine.
