History of the use of water power in Lobodice by Kojetín
Koutný, Vojtěch ; Haluza, Miloslav (referee) ; Hudec, Martin (advisor)
Energy is the driving force of the economies of countries around the world, without its use it would not be possible to achieve such great progress in science and living standards. However, in order for energy to be used, it must be created. This bachelor thesis will focus on the production of energy from a renewable source, which is a river. Specifically, the function and use of artificial water flow Bolelouc and MVE Lobodice.

Reversible swirl turbine
Palička, Miroslav ; Klas, Roman (referee) ; Haluza, Miloslav (advisor)
This diploma thesis describes hydraulic design of Swirl turbine, dedicated to be used for tidal powerplant and study possibilities of the turbine to work in turbine, reverse turbine, pump and reverse pump regime. From individual regimes, graphical characteristics of created hydraulic design were created and compared, using CFD simulations.

Modal analysis of the swirl turbine runner
Valo, Lukáš ; Fic, Miloslav (referee) ; Čupr, Pavel (advisor)
The bachelor’s thesis deals with modal analysis of the swirl turbine runner. The main aim was to determine natural frequencies and mode shapes of the turbine runner. Both detailed and simplified models of geometry of the turbine runner were analysed for two types of boundary conditions. The ANSYS program was used to carry out numerical simulations. Experimental measurement was realised to verify and to compare results of calculations.

Improving of hydraulic properties of swirl turbines
Kůrečka, Jan ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This diploma thesis describes design of blade geometry of swirl turbines with different blade row density for given parameters Q11 = 1,9 [m3s-1], n11 = 170 [min-1], H=2,5 m, and =0,8. Goal is to found out differences between designs with high count of runner blades and design with fewer blades. Comparison of computed characteristics of three, seven and nine bladed runners is given.

Application of bionics for hydraulic turbine blade design
Kaprinay, Zoltán ; Moravec, Prokop (referee) ; Rudolf, Pavel (advisor)
This bachelor’s thesis deals with application of bionics for girl turbine blade design. In the first part the basic theoretical concepts of bionics are explained, and there are different inventions described which are inspired by nature from both past and present. The description of the principle and fiction of girl turbine is followed by designing the blade. Calculations are based on real data for the girl turbine. In the end of the work there is the 3D model of designed blade.

The project of turbines for small water power plant
Dolinský, Filip ; Machů, Tomáš (referee) ; Haluza, Miloslav (advisor)
Bachelor thesis deals with usage of hydropower potential of river profile by small hydro powerplant, sollution by Archimedes and Swirl turbines is designed. In the first part, current status of hydro powerplants in Slovakia is described and obligations of the Slovak republic to the EU are analyzed. In the second part, basic division and knowledge about Screw and Swirl turbine are sumarized. The third chapter deals with design, calculations and comparison of different kinds of turbines. Most optimal sollution is analyzed, design parameters are elaborated and building cost and return of investment are calculated.

The affect of the blade length on the swirl turbine characteristic
Pavlíček, Jan ; Hudec, Martin (referee) ; Habán, Vladimír (advisor)
This thesis deals with the evaluation of swirl turbine measurement, which the length of the turbine blades was gradually reduced. The subject of the effect was influence of the length of the blades, especially the measured efficiency of the turbine, and the character assessment of the flow at the inlet and outlet of the impeller. The measured data were analysed using the computing workbook with macro support, which can be used to evaluate other measurements of similar character. The different behaviour of the turbine depending on the length of the blades of the impeller was shown in the characteristics of the turbine and velocity triangles. For the variant with the best efficiency achieved was constructed QH diagram used in the design of turbine parameters for a particular location.

The design of swirl turbine for the concrete locality for ČEZ
Šebela, Radek ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
This thesis deals with the design of water turbine enabling optimal utilization of hydro-energetic potential of given location (barrage on Úpa river) chosen by ČEZ a.s. company. Moreover, the option of multi-unit layout is discussed. Because of the low-head profile of given location, the technology of swirl turbine in siphon configuration was chosen. Technology of swirl turbine presents new modification of Kaplan turbine with no need of guide vane. Swirl turbine is characterized by its high discharge and high speed. The main part of this thesis is focused on hydraulic design of the turbine.
