Effect of model hydrometeors on the development of discharge from an artificial cloud of charged aqueous aerosol

摘要

The process of discharge initiation and propagation in clouds of a charged aqueous aerosol in the presence of coarse model hydrometeors has been experimentally studied. It is established that the development of a spark discharge in the gap between a charged aqueous aerosol cloud and a grounded plane depends on the parameters of hydrometeors, the site where a group of hydrometeors is situated, and the electric field strength. A group of conducting cylindrical model hydrometeors most effectively initiates a spark discharge between charged aqueous aerosol clouds. Optimum configurations of such a group for initiating and guiding a discharge are determined. Characteristics of the final stage of discharge from a charged aqueous aerosol cloud in the presence of model hydrometeors are analyzed.
