In this work, the properties of a one atmosphere uniform triphasic barrier discharge panel in a subsonic wind tunnel have been investigated. The power supplying system has been specifically designed for this application, by means of a PIC generated signal reference and some audio MOSFET amplifiers. Electric, fluid-dynamic and spectroscopic diagnostic techniques have been utilized to characterize the plasma. The discharge panel has been tested inside an open circuit blowing wind tunnel, at different power supply conditions and air speeds. Moreover, a phase transposition has been performed in order to investigate the influence of the three phase translating wave on fluid acceleration. All the diagnostics were applied to both the electrode connection schemes. Vibrational and rotational temperatures have been evaluated by means of spectroscopical techniques. Active and reactive power have been monitored by means of voltage and current probes, while fluid velocity on the top of the board has been measured with a Pitot probe.

Abstract
In this work, the properties of a one atmosphere uniform triphasic barrier discharge panel in a subsonic wind tunnel have been investigated. The power supplying system has been specifically designed for this application, by means of a PIC generated signal reference and some audio MOSFET amplifiers. Electric, fluid-dynamic and spectroscopic diagnostic techniques have been utilized to characterize the plasma. The discharge panel has been tested inside an open circuit blowing wind tunnel, at different power supply conditions and air speeds. Moreover, a phase transposition has been performed in order to investigate the influence of the three phase translating wave on fluid acceleration. All the diagnostics were applied to both the electrode connection schemes. Vibrational and rotational temperatures have been evaluated by means of spectroscopical techniques. Active and reactive power have been monitored by means of voltage and current probes, while fluid velocity on the top of the board has been measured with a Pitot probe.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
