    Dependence of Frequency and Phase Velocity of Plasma Jet Hydrodynamic Instability on Sound Velocity

  • Original language description

    In this work detailed study of dependence of oscillation paprameters of Rayleigh instability on the plasma flow. Property was performed by analysis of oscillations of light emitted by plasma jet. Plasma flow was generated by a water stabilized or hybridsteam-argon plasma torch with an external anode.The frequency and the phase velocity flow oscillations as well as the velocity of plasma.and sound velocity were determined for various argon flow rate and various arc currents. It was found that the frequency and the phase velocity of studied coherent oscillations linearly depend on the sound velocity.

    Závislost frekvence a fázové rychlosti hydrodynamické nestability proudu plazmatu na rychlosti zvuku

  • Czech description

    V této práci je detailně studována závislost oscilačních parametrů Rayleighovy nestability proudu plazmatu. Vlastnosti byly určovány z analýzy oscilací světla emitovaného proudem plazmatu. Proud plazmatu byl generován plazmatronem s vnější anodou a se stabilizací vodním vírem nebo s hybridní stabilizací parou a argonem. Frekvence a fázová rychlost oscilací proudu plazmatu a rovněž rychlost plazmatu a zvuku byly zjištěny pro různé průtoky argonu a pro různé proudy oblouku. Bylo zjištěno, že frekvence a fázová rychlost studovaných koherentních oscilací závisí lineárně na rychlosti zvuku.
