Abstract

Generator hladne plazme je kompleksan sustav u kojem se zbiva mnogo međusobno povezanih fizikalnih procesa. Modeliranje i analiziranje takvog sustava metodom konačnih elemenata (engl. FEM) može uvelike olakšati njegovo razumijevanje i kvalitetniji dizajn. U ovom je radu razvijeno nekoliko modela koji razlažu proces stvaranja hladne plazme na jednostavnije dijelove. Razvijen je 2D osno simetričan model generetora hladne plazme koji uključuje Teslin transformator i Geisslerovu cijev, no u njemu je primijećeno mnogo nedostataka i nepravilnosti. Zbog toga su razvijeni osnovni 3D model zavojnice pravokutnog poprečnog presjeka i 3D model realne primarne zavojnice Teslinog transformatora. Promatrane su osnovne karakteristike zavojnica i raspodjela magnetskog polja u okolnom prostoru.

Abstract (english)

The cold plasma generator is a complex system in which many interrelated physical processes occur. Modeling and analysis of such a system by finite element method (FEM) can greatly facilitate its understanding and better design. In this paper, several models have been developed that divide the process of creating cold plasma into simpler parts. A 2D axissymmetric model of the entire cold plasma generator, including Tesla transformer and Geissler tube, was developed, but there were many disadvantages and irregularities in it. For this reason, the basic 3D model of the coil of rectangular cross-section and the 3D model of the real primary coil of the Tesla transformer have been developed. The basic characteristics of the coils and the distribution of the magnetic field in the surrounding area were observed.
