Laboratory of electrophysics deals with experimental research of dynamic phenomena in electric arcs and thermal plasma jets including influence of these phenomena on interactions with injected solid particles. In most of experiments the thermal plasma is generated by an electric arc in a plasma torch.
 

    
 

The arc and plasma jet at the output of the plasma torch is observed using optical methods comprising the application of high-speed CCD cameras and multi-channel systems working with optical fibers and photodiodes.

  

Multi-directional recording is used for spatial reconstruction of dynamic processes in the plasma jet with a high temporal resolution.

               

The acquired experimental data are processed by image processing, by methods of correlation analysis, fast Fourier transform, wavelet analysis and computations of correlation dimensions.

Analysis of the complex dynamic phenomena in plasma flow, its stability, interactions with particles and surfaces and reproducibility of such processes parameters is crucial to various industrial applications. Among them we can name plasma spraying, plasma etching, dangerous agents decomposition or plasma chemistry in general. Experimental research conducted in our laboratory of electrophysics contributes to better understanding of processes in plasma with possible various industrial applications.
