Electric probe measurements in the anode area of a DC arc plasma torch at low pressure
Ondáč, Peter ; Mašláni, Alan ; Hrabovský, Milan
We measured radial profiles of the electric field, plasma electrical potential and electron temperature in the hot anode area of a hybrid water-argon DC arc plasma torch with an external anode. The measurements were made under different values of the ambient pressure, during the restrike mode with a constricted anode arc attachment or during a supersonic mode with a diffuse anode arc attachment. The results provide first experimental data on plasma electrical potential in that anode area.
Application of Electric Probes for Study of Structure of Thermal Plasma Jet.
Hurba, Oleksiy ; Hrabovský, Milan
Thermal plasma at atmospheric pressure was investigated. Electric probes and doable probe used as relatively simple and efficient tool for diagnostic of structure of flow field in thermal plasma jet. Were defined plasma potential and boundaries of the conducting region and their changing for the diferent operating modes of plasma torch.
Electric Probe Diagnostic of Supersonic Thermal Plasma Jet
Hurba, Oleksiy ; Hrabovský, Milan
This paper describes how electric probes can be used as relatively simple and efficient tool for investigation of structure of flow field in thermal plasma jet at the low pressure. A boundary of plasma jet between nozzle of plasma torch and ambient air was investigated by means of array of moving electric probes. Were defined boundaries of the conducting region and their change with pressure change
