Impact of high-frequency pulse electric field parameters on polarization and deformation of water droplet
micro-experiment was carried out and the impact of high-voltage high-frequency pulsed electric field parameters on deformation of water droplet was investigated.The results showed that polarization relaxation time decreased with increasing electric field strength
while the deformation of droplet
migration velocity of polarization charge and electric field frequency corresponding to maximum degree of deformation of water droplet increased.The lower the electric field frequency
the larger the emulsion capacitance and the smaller the polarization voltage
the less the polarization deformation.With electric field frequency deviating from natural frequency of water droplet
resonance effect and drop deformation were suppressed.With increasing duty ratio
electric field acting on the droplet and deformation of water droplet increased.Part of the electric field energy leaked through the oil phase when duty ratio was large
which resulted in smaller deformation of water droplet.The interaction between parameters of high frequency pulse electric field acting on polarized deformation of the droplet cannot be ignored.The research results laid good foundation for further investigation of high-voltage high-frequency electrostatic emulsion-breaking mechanism.
