The turbine regulation of the small hydro-powerplants
Horký, Jiljí ; Dobrovolný, Martin (referee) ; Stareček, Jakub (advisor)
This bachelor thesis deals with the regulation of water turbines in small-hydro power plants. The first chapter presents the basic theory of this issue. In the next following two chapters, the characteristics of individual types of turbines, their construction and construction of control mechanisms are introduced. With the help of velocity triangles is shown, how the flow conditions are changing during the work of control mechanisms and what influence the control has on the hydraulic machine.

The affect of the blade length on the swirl turbine characteristic
Pavlíček, Jan ; Hudec, Martin (referee) ; Habán, Vladimír (advisor)
This thesis deals with the evaluation of swirl turbine measurement, which the length of the turbine blades was gradually reduced. The subject of the effect was influence of the length of the blades, especially the measured efficiency of the turbine, and the character assessment of the flow at the inlet and outlet of the impeller. The measured data were analysed using the computing workbook with macro support, which can be used to evaluate other measurements of similar character. The different behaviour of the turbine depending on the length of the blades of the impeller was shown in the characteristics of the turbine and velocity triangles. For the variant with the best efficiency achieved was constructed QH diagram used in the design of turbine parameters for a particular location.
