| Abstract: | Taylor cone shape of double cavity electrode was studied by cavity needle-plate discharge device, and the factors affecting atomization effect were analyzed.The parameters of Taylor cone shape, cone length and cone angle at different voltages and separation angles were studied by processing the images taken by high speed camera with saftware.The results show that the discharge inhibition of double cavity can be weakened by bending processing between discharge inhibition. Under the same length, compared with that of single cavity electrode,the atomization effect and Taylor cone of double cavity electrodes is better. And regarding to the separation angle of double cavity electrode, when the separation angle is 60°, the atomizing effect is the best.Therefore, when the separation angle of the double-cavity electrode is 60°, it can be used as the optimal electrode.The best Taylor cone shape is obtained when the voltage is 25 kV. |
| Keywords: | electrostatic atomization double-cavity electrode Taylor cone morphology separation angle |
