ION INJECTORS FOR SINGLE- AND TWO-PHASE ELECTROGASDYNAMIC GENERATORS.

Abstract

Systems suitable for the injection of ions into electrogasdynamic (EGD) generator devices were built and tested. The mechanism of injection was based on a corona discharge, whereby ions moving through an electric field can be intercepted by a gaseous flow. The intercepted ions are of one polarity, insuring selective ion injection. Two types of injector units were investigated. One was a molecular ion device which produced ions directly from the carrier gas, and the other created larger sized ions, resulting in an aerosol flow. The latter consisted of passing saturated steam through a corona discharge and injecting it into an air stream. In order to aid the injection process, the wake of a cylinder in the air stream was utilized in both cases. Most of the work done here was devoted to the design and testing of the aerosol flow device. The degree of success was moderate. (Author)
