Abstract

Kavitacija je proces, pri katerem zaradi spremembe tlaka v tekočini nastanejo kavitacijski mehurčki. Znano je, da lahko s pomočjo kavitacije pospešimo nekatere kemijske procese, vendar fizikalno ozadje le tega še ni popolnoma pojasnjeno. Večjo kemijsko aktivnost povezujemo s prisotnostjo udarnih valov in nastanka mikrocurkov. V raziskovalnem delu mojega diplomskega dela smo z laserskim pulzom generirali kavitacijski mehurček v kiveti napolnjeni z vodo in vstavljenim zračnim mehurčkom. Proces smo opazovali s pomočjo hitre kamere, pri obdelavi rezultatov smo se osredotočili na smer kolapsa in nastanek mikrocurka.

Secondary title: Cavitation bubble dynamics in between two free surfaces
Secondary abstract: Cavitation is process by which cavitation bubbles form due to a change in pressure in a liquid. It is known that cavitation can accelerate certain chemical processes, but the physical background is not yet fully understood. The increased chemical activity is associated with the presence of micro-jets and the formation of microbubbles. In this research a laser pulse was used to generate a cavitation bubble in a cuvette filled with water and an air bubble inserted. The process was observed using a high-speed camera, and the results were processed by focusing on the direction of collapse and micro-jets formation.
