Liquid Atomization in Electrostatic Field

抄録

The effect of static electricity on the disintegration of a liquid jet and on the droplet size of a distilled water is investigated by using an injection syringe. The following results are obtained : (1) Static electricity increases the rate of atomization and creates peculiar phenomena such as sinuous, zigzag, winding and wavy flows. (2) At the jet stream velocity of about 1 m/sec, the effect of static electricity on atomization is the most remarkable. (3) In the regions of sinuous and wavy flow, droplets descend in a circular spiral motion. (4) In the regions of zigzag and winding flow, the droplets descend in an elliptic spiral motion. The local mean droplet diameter measured along the major axis is greater than the one along the minor axis. (5) The local mean droplet diameter becomes smaller as the distance from the center becomes greater.
