Abstract
The kINPen MED atmospheric pressure plasma jet is now undergoing clinical
studies that are designed to investigate its suitability as a device for use in plasma
medicine treatments. This paper describes dimensionless studies of the synchronizing
oscillatory gas flow through the nozzle followed by electro-acoustic measurements
coupled with the discharge photo emission. The plasma jet operates in the burst mode of 2.5 KHz (duty cycle = 50%), within a neutral argon Strouhal number of 0.14 to 0.09 and
Reynolds number of 3570 to 5370. In this mode the jet acts like a plasma actuator with
an anisotropic far field noise pattern that is composed of radiated noise centered at 17.5
kHz; +20 dB, and the expanding visible plasma plume and cooled gas recombine along
the jet axial flow (1-2 kHz peak that diminishes at a rate of -1.7 dB.kHz-1).
