Temperature dependence of dc corona and charge-carrier entrainment in a gas flow channel

Current-voltage (I-V) data for positive and negative polarity point-to-plane geometries are reported for g-as 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.
