Abstract
Electrostatic atomization has been studied to inject charged water droplets into oil in a microchannel reactor system. With a negative dc voltage, Taylor cone was formed and the droplets were injected into oil within 1/30 sec. The injection took place periodically with interval of a few seconds when the dc voltage was maintained. Using water, droplets of 10.7 μm average diameter with standard deviation of 3.8μm were injected into rapeseed oil. When 50% glycerol was used, droplets of 6.7μm diameter with SD of 2μm were generated. The electrostatic atomization was proved to be effective in a microchannel system to produce charged fine droplets into oil. This will provide a pump-free system as the droplets can be manipulated using electrical force. The results require further improvement to produce more mono-disperse droplets.
