Hydraulic solution of the swirl turbine for locality of Rosenauer mill
Pavlíček, Tomáš ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This thesis focuses on the design of a swirl turbine for the site of Rosenauer Mill, where the gross hydraulic head HB is 1 m and the flow rate is Q is 1.6 m3/s. The beginning of the work is dedicated to microturbines and explains why a swirl turbine is suitable for this location. The procedure applied for developing the hydraulically active surfaces of the turbine is then presented. Firstly the design of the blades is based on analytical formulas, which are further refined using the CFX Ansys program. The turbine is closely affected by the inlet and draft tube, therefore their design is also included in this thesis. The hydraulic calculations yield the resulting parameters and characteristics of the designed turbine, calculated from the entire assembly using CFD computations. The final section of the work is devoted to the design of main structural components such as the gear, shaft, and bearings. The hydraulic design developed in this thesis serves as the basis for implementing the swirl turbine and constructing a small hydraulic power plant at the Rosenauer Mill.

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.

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.

The swirl turbine design for small water power Hovězí.
Oliva, Štěpán ; Neumayer, Oldřich (referee) ; Haluza, Miloslav (advisor)
The aim of this work was to develop a proposal regarding hydro-energy potential of small flows of water through the city „Hovězí near Vsetín“. The available water energy was used for running a Swirl Turbine featuring a siphon arrangement. This new concept makes use of a modified Kaplan Turbine, operating at small water heads. It operates also at higher revolutions and has higher discharge.

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.

Using of 3ds Max in heavy current engineering
Loško, Petr ; Kuchyňková, Hana (referee) ; Huzlík, Rostislav (advisor)
I would like to outline the basic procedures of creating a visualisation in 3D Max application. My thesis should answer the question, whether 3D Max is suitable for modeling, visualization and animation in heavy current electrotechnics. The theoretical part of the thesis will be followed by a practical part, demonstrating the procedures by creating a vortex turbine model.

Hydraulic properties of siphon and direct flow swirl turbine
Hudec, Martin ; Šulc, Jan (referee) ; Veselý, Jindřich (referee) ; Habán, Vladimír (advisor)
Non-stationary processes are associated with the operation of water machines. They are important for their reliable and safe operation. Prediction and modeling of such states using a 1D mathematical model verified on a model in the laboratory is an advantage. The work is focused on the description of a pair of transient states that are related to siphon turbines and their operation. Determination of critical flow values for inducing a suction effect and, conversely, calculation of the minimum size of the flow coefficient for safe stopping. The experiments were performed on a laboratory model and compared with operational data from a small hydroelectric power plant Želina.
