Electric Discharge Flow Interaction in Parallel and Cross-Flow Electric Fields

摘要

This work deals with an evaluation of power capacity of two glow discharge orientations with respect to a flowing medium, namely, parallel and cross-flow. A test section was designed and fabricated to compare the effects of flow, turbulence generated by perforated plates, electrode spacing and electrode length on the cross-flow electric field to the performance of an existing parallel flow electrode set of the same type: positive pin-rack (anode) and plane (cathode). Discharge data and photographs are presented. Flow and turbulence are stabilizing. The parallel flow electric field discharge permits higher power than the cross-flow field. Increased cathode length in the streamwise direction produces a small detriment to discharge power. (Author)
