EXPERIMENTAL STUDY OF THE HEATING OF GAS FLOW BY HIGH-FREQUENCY DISCHARGE

Abstract

An experimen al investigation was carried out to determine the feasibility of using a radio-frequency discharge to heat a supersonic gas stream. Experiments were conducted with both axisymmetric and two-dimensional supersonic nozzles with the RF discharge created in the supersonic gas flow. Temperature measurements in the flow field downstream of th discharge indicate a definite temperature rise in the decaying plasma. Calorimetry measurements show hat it is possible to add up to 40% of the energy available at the discharge plates to the gas stream. It is concluded that radio-frequency discharge heating is a feasible method of heating a supersonic gas stream. (Author)
