Compressor Turbocharger Design
Domanský, David ; Škorpík, Jiří (referee) ; Fiedler, Jan (advisor)
The master's thesis deals with compressor turbochargers used for supercharging of combustion engines. The aim of the thesis is feasibility study of compressor surge limit simulation. First of all the principle and purpose of supercharged combustion engines is described and the compressors' types using for supercharging are mentioned as well. The main part of the thesis is focused on flow instabilities and their influence on compressor operating zone. There are mentioned some possibilities of operating zone extension. The practical part comprises the simplified computation of a one stage of centrifugal compressor and flow analysis by means of CFD simulation.

Combi-cycle power plant
Tkachuk, Andriy ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This master thesis follows the bachelor thesis with the same name. It is looks into the analyses of the combi-cycle, the advantage of which is high efficiency and easy separation of CO2 for its storage and further usage. It introduces the Graz cycle, its thermal balance a basic arrangement. The calculation is attached in a separate .XLS file. At the end of the thesis, the result of the calculation is interpreted and the conditions under which the project would be realized are outlined.

Wind power plant in a chosen locality
Dohnal, Petr ; Škorpík, Jiří (referee) ; Martinec, Jiří (advisor)
This master thesis deals with problematic wind power plants. There are described advantages and disadvantages of wind power plants and their environmental impacts. Thesis include chosen locality for wind power plant, chosen fitting types of turbines and calculation which choosing turbine for chosen locality. There are accomplished parametric studies of main parameters. From this study is chosen best fitting model of wind turbine. In the end are adduced statistics from Czech Republic, Europe and world.

Offshore and inland type of wind power
Chromec, Tomáš ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This bachelor‘s thesis focuses on wind energy sector. The first part describes the modern history of this industry. The brief description of the main differences between onshore and offshore wind farms followed an extensive chapter, which describes the diversification of wind power solutions and diversification in the case of wind farms located on the sea. Fluctuating needs for backup power sources in this work is included in chapter, which briefly describes the most appropriate energy storage devices. This is followed by section dealing with the economics of wind turbines. Possible negative impacts of wind energy are discussed in the final chapter about environmental impacts associated with wind power applications.

Technologies for electricity storage
Pochylý, Jiří ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
The point of this work is to compare and to describe basic types and principles of electric storage systems. With the increasing imbalance between consumption and generation of electric energy there is a need for integration of electric accumulators to the electric grid. Technologies for electric energy storage can be divided into several types, which differ in form and conversion of energy. These technologies are suitable for specific industrial applications.
