AC Plasma Anemometer in a High Speed Preionized Hydrogen Jet

ORAL

Abstract

Measurements in a high-speed, preionized, low pressure hydrogen jet using a novel AC-driven glow discharge flow sensor are

presented. These results examine the sensitivity and voltage-current characteristics of a plasma sensor with and without the presence of a background RF plasma. These results extend the utility of the plasma sensor to a regime of rarefied and reactive, high speed gases. Recent experiments examine the effects of electrode geometry, AC frequency, and background ionization on the plasma sensor response.
