Nano and microbubbles created by cavitation
 Harazin, Přemysl ; Sluše, Jan (referee) ; Rudolf, Pavel (advisor)
This work solves the problematics of distinguishing tiny bubbles and particles as well as the thermodynamics of bubbles and their creation. The process of cavitation is described in the first part of the thesis. The problem of visualisation and counting the number of bubbles is described in the experimental part as well as the posibility of influencing the stream through the input of obstacles. Problem with visualisation was dealt with laser beam shining through the transparent tube with software postprocessing. The issue of influencing the stream was dealt with input of the strainer into the stream. Results of these experiments are, that with good ambient light situation, the laser beam ensures good visualisation of bubbles and particles and therefore the posibility of counting the number of bubbles with the help of a software. The usage of strainer helped to create bigger number of tiny bubbles.
