| Abstract: | Current–voltage (I–V) data for positive and negative polarity point-to-plane geometries are reported for gas flows transverse to the axis of the emitters. Air and nitrogen flows of 0–5 m/s were considered in the experiments and temperatures in ranges of 213–493 K in nitrogen and 283–493 K in air. Entrainment of charge carriers from the individual corona and positive–negative polarity emitter-pairs was considered towards understanding the static elimination process for downstream targets in the gas flows. |
