Computational results for DC air arcs burning in a turbulent round jet are reported and compared with experimental results. It has been found that turbulent energy transport inside the high temperature arc core is not important. The interaction between the arc and the jet generates pressure waves resulting in arc voltage oscillating with a period of approximately 0.5 ms. The amplitude of such voltage oscillation depends on current and the width of the jet.
