Application on Wavelet Analysis and Fournier Transform to Investigations of Thermal Plasma Spatio-Temporal Dynamics

Popis výsledku v původním jazyce

Electric arc plasma generated by the plasma torch (plasmatron) was analyzed. Electric arc and resulting plasma jet were observed from four directions in two parallel planes perpendicular to the jet axis and arc current and voltage were also recorded synchronously. The record lengths and time resolution were sufficient for the application of the FFT yielding a detailed view of the oscillation phenomena in the plasma flow and for comparison with oscillations of voltage and current. Significant oscillations were identified and their planar distributions examined. Wavelet analysis was used for temporal dynamics investigation yielding information about structures dynamics. Different types of structures were identified and their mutual influence is described.
