Abstract

The spatial distribution of gas temperature in air plasma jet of dc glow microdischarge has been determined. The temperature field was measured by a thermocouple probe and compared to schlieren images. The jet can be separated in the radial direction into three characteristic regions with clearly pronounced boundaries. The central region represents a narrow hot zone corresponding to the visible plasma plume, in which the gas temperature varies from 50 to 200°C depending on the air flow rate and distance from the anode. This zone is surrounded by a warm “coat” of ~1-cm diameter and a temperature within 30–50°C. The outer region represented ambient air at room temperature. The zone of temperatures above 50°C did not extend to a distance above 3 cm from the output nozzle of the discharge cell.
