Diagnostics of plasma jet instabilities using fast shutter imaging
Original language description
The structure and stability of plasma jet were studied on the basis of statistical analysis of the images of the jet taken by a fast shutter camera. The space distribution of the mean value and the standard deviation of image brightness were evaluated from a sequence of images. The short exposure time ensures imaging of the momentary state of the jet while analysis of sequence of images provided information on jet fluctuations. The effects of arc current and anode position on thermal plasma jet were investigated. Arc power increase led to higher fluctuations of the jet, it although causes increase of the jet length.

Diagnostika proudu plazmatu s použitím rychlostní kamery
Czech description
Struktura a stabilita proudu terminálního plazmatu byly studovány pomocí statistické analýzy fotografií plazmatu. Snímky byly pořízeny rychlostní kamerou z expozičním časem kratším než kmity a nestability plazmatu. Prostorové rozdělení nestabilit plazmatického proudu bylo znázorněno a analyzováno pro různá nastavení plazmatronu.
