Aerodynamic design of wind turbine
Žabka, Marek ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This Master’s thesis focuses on the wind turbines. It describes the basic attributes of the wind energy and the wind potential of Slovak Republic, as well as the environmental impact of this sector. Meteorological data for the selected location are processed according to the Weibull distribution and they are used for the aerodynamic design of the wind turbine blades. Aerodynamic design is processed by using two methods. The first is the blade cascade theory, which is used to design prismatic and twist blades. The second method is called the blade element momentum, which is used to design wind turbine but only twist blades are designed by using this theory. Calculated aerodynamic shapes are compared and the best economic solution for the selected location is chosen.

Design of tidal turbine
Mahdal, Ondřej ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
The present time demands emission-free and carbon-free sources of energy. This fact is not only subject of international agreements and European Union regulations, but also the state of environment points out to an essential change in energy generation of mankind. Tidal stream provides very stable and predictable source of “green” energy. Compared to other renewable energy sources tidal stream turbines in exceptional localities are able to supply energy continuously, making them base load source. The aim of the thesis was to create an extensive document with recent tidal stream power information, which has not been available in Czech language yet. Last part of the research is focused on co-locating tidal stream and off-shore wind turbines. Second part of the thesis is dedicated to aerodynamic design of single-stage horizontal axis tidal stream turbine with rated electric power of 1 MW. Calculation according to the blade cascade theory was used to design blade geometry and to find rotor diameter of 14 meters for rated stream velocity of 3.05 m/s.
