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.

Swirl turbine design
Šperka, Oldřich ; Skoták, Aleš (referee) ; Haluza, Miloslav (advisor)
The purpose of this diploma work is to predict the action of the swirl turbine in a siphonal configuration using the potential energy provided by the river Úpa near the city Jaroměř. The hydraulic predictions of the turbine impellor were based on calculation made using the CFD program Fluent. The measurement of the draft tube and the strength calculations of the turbine blade and spindle are based upon the theories, experiments and finally on the knowledge gained from the test models constructed. The results of this project can be used when considering the viability of a small hydraulic power plant.

Hydro power station design
Novák, Pavel ; Grepl, Robert (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with designing a small hydraulic power plant, where a swirl turbine is conected to a unique synchronous working, which will offer a reliable and easy installation of the hydraulic power plant. As a result a wider potential of energy could be produced from renewable resources. The use of a narrow rottor as a holder of the permanent magnets is the biggest difficulties of this design.

Adaptation of historical technical facility on the small hydroelectric power
Čermáková, Klára ; Sluše, Jan (referee) ; Hudec, Martin (advisor)
Small hydroelectric power stations are the topic of this bachelor thesis which can be divided into three parts. The first one describes a history of utilising water energy, elementary types of hydropower projects, and classification of hydroelectric power stations. The second part is focused on small hydroelectric power stations. Finally the acquired knowledge is used in the last part describing the proposal of an adaptation of the water mill in Lomy to a small hydroelectric power station.

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.

The influence of the hub on discharge and efficiency of the swirl turbine
Husák, Martin ; Koutný, Luděk (referee) ; Haluza, Miloslav (advisor)
The aim is to determine by numerical modeling the influence of the hub on discharge and efficiency of the swirl turbine. The first part summarizes the theoretical knowledge about water turbines. In the main part is done hydraulic design of turbine, create model in Inventor, export geometry in Gambit and build mesh. Then it is described the solution methodology in Fluent, evaluation of computed data and their presentation in the form of tables and graphs

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.
