Measuring of Velocity Profiles in Liquids by Using of UVP
Kárník, Jan ; Stejskal, Jiří (referee) ; Štigler, Jaroslav (advisor)
The following bachelor's thesis deals with one possible way of determination velocity profiles in liquids. Content of the thesis is focused mainly on the method of the UVP (Ultrasound Velocity Profile), on the ways and principles of measuring, on its pluses and cons and it´s comparison with the other conventional methods, like for the example the PIV (Particle Image Velocimetry) and LDA (Laser Doppler Anemometry). There is also the possible placement of the transducers to the measuring system discussed. Furthermore the thesis deals with trouble in the test measurement. At the beginning this work deals with familiarization with principle and function of the measuring device and with the device for the method UVP itself. Apart from the UVP measuring method the thesis also deals with short description of the competitive methods – PIV, LDA, which are used to measure the velocity profiles nowadays. Particular attention is given to the PIV method, which significance is currently growing. In conclusion, there is comparison of different methods with the UVP method made and there are the future steps to realize the successful measurement with UVP method also discussed.

Small Hydro Power Plant of The Fountain Type
Vintr, Martin ; Haluza, Miloslav (referee) ; Štigler, Jaroslav (advisor)
The main target of this bachelor´s work is dealing with small hydro power plant, especially these plants of the fountain type. The first chapter deals with description, the main division of hydro power plant and their building construction. There is hydro engine and their individual parts in the second chapter. These engines are then given in context with using of hydro energy and their using in hydro power plant of the fountain type. There is also design concept of stock inlet into turbine. Not just theory but also practical construction are showed here to be compact for better understanding of these power plants in the third chapter.
