Experimentální analýza vícefázového proudění v hydraulice

Abstract

Master’s thesis is dealing with the issue of multiphase flow in hydraulics. The literature review focuses on the phenomenon of cavitation, its negative effects on hydraulic systems, and software used for evaluating bubble parameters. For the practical part of the thesis, a hydraulic circuit was designed and assembled in a laboratory to perform experimental analysis. Entrained bubbles in the oil flow were captured using a high-speed camera. The measured data were processed and evaluated graphically. Furthermore, bubble images were analysed using Fiji software and the results were compiled into graphs.
