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.
The design of swirl turbines for processing of remaining hydraulic energy of the hydraulic structure Chocerady
Sedláček, Jiří ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This diploma thesis deals with hydraulic potential energy of water flows. It also deals with Swirlturbine which is used for water flows with low fall. The optimal design of Swirlturbine at hydraulic structure Chocerady was the main part of this diploma thesis. Part of the diploma thesis is proposal of power plant, solution inlet and inlet swirls, next vent valve and the issue of the draft tube. The thesis includes the proposal of belt gear and strenght analysis of shaft and bearings.
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.
The design study of the modular swirl turbine solution
Brabenec, Ladislav ; Haluza, Miloslav (referee) ; Pochylý, František (advisor)
This Bachelor Thesis focuses on structural design of a swirl turbine with a disc generator with a subsequent detailed elaboration of technical documentation for a successful production a testing prototype.
Design of high-specific speed hydraulic turbine with contoured shape of the runner blade
Fojtíková, Marcela ; Haluza, Miloslav (referee) ; Rudolf, Pavel (advisor)
This master thesis is devoded to examination of influence of bumped leading edge of hydraulic turbines ruber blade to characteristics of blade cascade. Thesis is based on hydraulic turbine which countoured/bumped leading edge of blade was created using previous studies on NACA profiles. The main goal of this thesis is to Compare shaped leading edge with flat leading edge using CFD calculations. Programms like SolidWorks and Gambit were used to calculate geometrics and meshes.
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.
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.
