Adaptation of the water mill
Vašek, Lubomír ; Žák, Radim (referee) ; Hudec, Martin (advisor)
This bachelor thesis deals with adaptation of a water mill in Liboš to a small hydro power plant. Basic principles, functions and significance of each device are summarized and explained there. The thesis should provide a coherent description of SHPP to a reader who is unfamiliar with the topic and initiate him into the problems partly.

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.

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.

Self-priming pump
Urban, Jiří ; Hudec, Martin (referee) ; Pochylý, František (advisor)
Diploma thesis is focused on self-priming pump 25 - OVE Sigma pumpy Hranice s.r.o., for its function is essential the ejector which is placed in the body of the pump. On the basis of the results of measurements there are designed construction modifications using a mathematical model. For the first time were made measurements to verify the self-priming capability with determining the maximum suction height.

Study of hydroenergy potential exploitation of given location
Kollár, Martin ; Hudec, Martin (referee) ; Rudolf, Pavel (advisor)
For the objective of my Bachelor`s thesis I chose an assessment of hydropower potential and a design of machinery in the small hydropower plant construction on the river Váh in Trenčianske Biskupice site. I divided hydropower potential into three parts. First part is the past then present and last is future status. I have subsequently used these information in the design of machinery, including turbine and its associated penstock and draft tube. Part of my thesis also contains appropriate design solution for control gate of intake and outflow, trash rack and trash rack machine. I prepared and presented two possible alternatives together with the drawing documentation which are at the end of my paper compared and evaluated.

Adaptation of a small hydropower facility
Doseděl, Jakub ; Šedivý, Dominik (referee) ; Hudec, Martin (advisor)
This bachelor’s thesis is about small hydropower facility. First part describes elementary types of hydropower facilities and classification of waterpower engines. Second part deals with legislation connected with permission issued by public law enabling construction and operation of a small hydropower facility and with promoting renewable energy sources.

Adaptation of the Watermill
Pavlík, Jan ; Hudec, Martin (referee) ; Klas, Roman (advisor)
The bachelor´s thesis is composed of two parts. In the first part, there is a generally discourse about small water power plants, their structural design, mechanical equipment and economical efficiency and its function is to create the basic conception of the waterwork. The second one deals concretely with the small water power plant in Crhov, that was rebuilt from the original mill by Mr. Petr König in 1990s.

Cavitation erosion
Lecnar, Lukáš ; Hudec, Martin (referee) ; Rudolf, Pavel (advisor)
This bachelor’s thesis focuses on cavitation erosion and it is divided into two main parts. The first part is devoted to the search of cavitation erosion focusing on erosion mechanisms. In the first chapter of this search is briefly described cavitation process and different types of cavitation are listed here. Hydrodynamic cavitation which is the key type for this bachelor’s thesis is described in the following chapter. The final and the most extensive chapter is devoted to cavitation erosion of solids which is largely associated with the effects of the mechanical action of the fluid. The second part is devoted to the experimental study of cavitation erosion of samples. The goal was to document the experiment which was carried out in order to gain knowledge about the material removal by cavitation erosion.
