Features of a supersonic inductively coupled plasma small wind tunnel that can obtain high electric conductivity despite low input RF power are numerically examined by means of an axisymmetric r–z two-dimensional numerical analysis. The working gas is Argon. The stagnation pressure and temperature are 10kPa and 600K, respectively. The RF power is less than or equal to 1kW. Numerical results demonstrate that when the RF induction coil is set up in the supersonic region of nozzle (case-1), the plasma produced by RF Joule heating has much stronger thermochemical nonequilibrium state compared to the case that the RF induction coil is set up in the subsonic region of nozzle (case-2). As a result, the electrical conductivity in the test chamber in the case-1 is about two times higher compared to that in the case-2.
