Název v původním jazyce

Mapping of thermal plasma jet non-linear dynnamics in reconstructed phase space

Popis výsledku v původním jazyce

Thermal plasma jet optical radiation was observed by arrays of optical fibers and by a high-speed CCD camera. We then use the method of time-embeddings for reconstruction of dc plasma torch dynamics in the reconstructed phase space. Different propertiesof the plasma flow dynamics and dependence of this dynamics on input conditions (gas flow rate) are then described. We focused on non-linear and chaotic phenomena and tried to estimate the correlation dimension related to the (supposed) strange attractorof the dynamics. Sufficient spatial resolution allowed us to map the distribution of this estimated correlation dimension in different areas of the plasma jet and to compare it with the distribution of significant oscillations. This offers alternative method to describe the dynamics and provides strong tool for the analysis of the stability of plasma torch working conditions.
