Abstract
Lateral oscillation of a wire electrode occurs when high dc voltage is applied between wire and plate electrodes with corona discharge, and also the string that is stretched in parallel to the wire electrode. The fluid force on the wire due to corona wind was assumed to be one of main reasons for the outbreak mechanism of the oscillation. In this paper, in order to investigate the relationship between corona wind and string oscillation, the flow field is calculated numerically as the moving boundary problem. Moreover, the theoretical discussion is also given.
