Experimental testing of minimixer for waste water treatment
Luňák, Pavel ; Štefan, David (referee) ; Rudolf, Pavel (advisor)
This thesis deals with various ways of mixing mainly liquids. The theoretical part is devoted to the distribution of mixers, including a description of their characteristics, advantages, disadvantages and applications. The experimental part is devoted to the measurement of minimixers, which were developed and manufactured V. Kaplan Department of Fluid Engineering. This section contains a proposal of measuring ciruit to determine the hydraulic characteristics of minimixers and the degree of mixing. The measurement results and their evaluation is summarized in the conclusion.

Hydraulic characteristics of the cavitation nozzles
Gríger, Milan ; Habán, Vladimír (referee) ; Rudolf, Pavel (advisor)
The main goal of this thesis is the examination of hydraulic characteristics for different cavity nozzles, influence of liquid rotation and visualization of cavitating flow. Thesis is divided into two parts, theoretical and practical. Theoretical part deals with the description of cavity - creation, development and its extinction. This part also contains description of vortex flow and basic vertex models. Practical part compares nozzles performance experimentally. The aim of experiment was to measure hydraulic characteristics and their comparison. Jet performance was judged using visualizations and measured data was processed in Microsoft Excel and Parametr.

Cavitating flow in perforated disc
Kubina, Dávid ; Kozák, Jiří (referee) ; Rudolf, Pavel (advisor)
The main goal of this bachelor thesis is to measure hydraulic characteristics of five round plates perforated with several circle orifices installed in the pipeline. The main condition was to preserve constant cross section of the holes in sum. Theoretical part of the thesis is focused on the basics of hydrodynamic cavitation and its practical usage in the industry. The experimental part of the paper deals with hydraulic characteristics of each shield perforated by varying number of orifices and also includes mutual comparison. Also high speed camera was used to detect the length of cavitation zone, although these results are not included in the conclusion of the thesis.
