Portable water pico turbine design, production and basic parameters verifying
Tománek, Ladislav ; Haluza, Miloslav (referee) ; Štigler, Jaroslav (advisor)
The aim of this diploma thesis is to design, manufacture and measure the characteristics of a mobile water pico turbine. More precisely, it is an experimental construction of a mill wheel. The first part of this document is describing the design and manufacture of the turbine. This part focuses mainly on the construction of water wheels with different sizes of buckets and on the nozzle supplying water to the turbine. There is also a CFD simulation of pressure loss of nozzle. The second part of the thesis is focused on the processing of data that were measured in the laboratory, including the determination of uncertainties. The measurements were performed for different turbine settings such as flow, speed, different wheel shapes and different positions of the nozzle distributing water to the wheel. For individual turbine settings are created characteristics, from which maximum powers and maximum efficiencies parameters are determined.

Restoration of water management at the water mill
Chrástová, Veronika ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The water mill in Příkrakov has been out of operation for several decades. The current owners decided that the mill wheel could be put into operation again. Therefore, the subject of this work is precisely the suggestion of how to get the water wheel of the mill running again. The design begins in the Ležák creek, where a weir with a floodgate will be placed. A floodgate will separate part of the flow from the creek to the millrace. From the millrace, the water goes to the mill reservoir, from which the water already flows through a reinforced concrete channel directly to the mill wheel. The entire design is supplemented by calculations which result is the total power and energy that the mill wheel is able to produce.
