Description unsteady operating conditions of siphon swirl turbine
Krejčiřík, Stanislav ; Habán, Vladimír (referee) ; Hudec, Martin (advisor)
The master´s thesis focuses on the behavior of the siphon turbine during unsteady flow. There are two possible conditions. The first condition involves commissioning the turbine. In this situation turbine works like a pump. In the second case, it includes shutting down the turbine by aerating the siphon and thereby breaking the water column. This thesis deals with the second case, where the results of the experiment and the mathematical model are compared.

Adaptation of the water mill
Dobšáková, Lenka ; Uttendorfský, Petr (referee) ; Hudec, Martin (advisor)
This bachelor’s thesis is about adaptation of the water mill Cacovice. The first part is a description of the history of water mills and mill history in Cacovice. The second part deals with small hydroelectric power station, their functions and distribution. The third part describes the technical part of the small hydroelectric power station Cacovice and the fourth part is a proposal for a new Kaplan turbine, which could replace the existing Francis turbine.

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.
