Modeling of cavitating flow
Frölich, Kamil ; Klas, Roman (referee) ; Rudolf, Pavel (advisor)
his thesis deals with the problems of cavitation flow in a Venturi tube. It is made for a multi-phase (water-vapour) flow calculation of two geometry tubes. Results of numerical calculations for the flow geometry (dimensions) are compared with performed experiment. Numerical flow calculation was performed in the Fluent 2.3.26.

Integral sediment sampler
Zouhar, Josef ; Štigler, Jaroslav (referee) ; Rudolf, Pavel (advisor)
This thesis deals with analysis of flow inside integral SPM sampler. Flowing is described for one-phase flow and multi-phase flow (water-solid particles) approaches. Results of computational modeling and experimental modeling are compared. Experimental box was constructed and its construction is noticed. Methods of used computational and experimental modeling are described. Optimal computational model is recommended. The theme of this thesis was chosen in co-operation with Czech Geological Survey whitin the frame of project MŽP „SP/1b7/156/07“.

Design of small hydropower plant for specific location.
Paštěka, František ; Rudolf, Pavel (referee) ; Štigler, Jaroslav (advisor)
This master's thesis is specialised in designing of small hydropower plant for specific location. In work should be designed suitable turbine for parameters found on the site, then created a basic project documentation of small hydropower plant with all devices and used principles, so that the plant would be capable of operation. In the next part of thesis should be extented the calculation of flow in the turbine delivery and assessed effect of geometry of turbine delivery on the flow.

Experimental testing of hydrocyclone
Juráš, Filip ; Hudec, Martin (referee) ; Rudolf, Pavel (advisor)
This bachelor thesis is focused on experimental testing of hydrocyclone. The work is divided into two parts. The first part describes basic parts of hydrocyclone, dimensions, and operating parameters of the tested hydrocyclone and principles of its work. The second, practical part, describes the general preparation of the experiment, which started with searching for a suitable material and continued to the filter device used for particle separation.

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.

Shape optimization of hydraulic turbine diffuser
Hliník, Juraj ; Popela, Pavel (referee) ; Rudolf, Pavel (advisor)
This bachelor thesis deals with mathematical optimization focusing on the shape optimization in fluid mechanics with help of a CFD software. More specifically, it comprises the shape optimization of a swirl turbine draft tube with a specified rotational symmetry and the whole process is realised with Nelder-Mead and BFGS algorithms. The main object was to maximalize the pressure coeficient, with help of the algorithms which were implemented in Matlab software.

Dancing liquid - vibration eigenmode shapes of liquids
Urban, Ondřej ; Pochylý, František (referee) ; Rudolf, Pavel (advisor)
This bachelor's thesis deals with phenomena connected with vertically oscillating liquid layer, particularly with Faraday waves and liquid atomization. More in detail it deals with the linear mathematical model for vertically oscilating inviscid and incompresible liquids by Benjamin & Ursell (1954). It also presents the appearance of these and other phenomena connected with liquid vibration in practical applications. Furthermore, results of experiments are presented. Their aim was to find some eigenmode shapes using the linear model and also to document some of their properties. Final part is aimed to the design of an experimental device for visualization of vibration eigenmode shapes of liquids.
