Cross-flow turbine - reverse engineering
Řeha, David ; Haluza, Miloslav (referee) ; Hudec, Martin (advisor)
This thesis deals with the reverse engineering of the cross-flow turbine. The departement of fluid engineering was given a model of the cross-flow turbine many years ago, however it has never been put into service and nothing is known about it. This thesis describes the analysis of the turbine design, the replacement of parts that occurred to bring the turbine into service, and how the turbine was modified for the process itself. Furthermore, based on the dimensions obtained estimation of the parameters, for which the turbine was designed, was carried out. A measurement track was set up for that purpose and the turbine was measured in the laboratory conditions. Real values of the turbine parameters and the subsequent evaluation of the universal characteristics of the turbine were obtained by the measurement. This thesis includes also the construction of a measurement tutorial for students.

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.
