A numerical study is made of the structure of a swirling argon flow with atmospheric pressure in a closed tube duct with an asymmetric gas outlet, a localized heat source simulating gas heating by a longitudinal pulse repetitive HF discharge, and the source of an acoustic field simulating sound generation by discharge pulses. It is shown that, at supercritical amplitudes of the acoustic field, helical gas-dynamic and thermal flows capable of inducing the formation of a discharge channel with a structure that is close to the shape of a helical flow can form. The results are shown to qualitatively agree with the known experimental data.
