Bio-gas power plant
Mészáros, Gabriel ; Joch, Lukáš (referee) ; Pospíšil, Jiří (advisor)
The master’s thesis is focused on the possibility of using biodegradable materials (animal manure, energy crops, crop waste) in a biogas plant. The first part deals with the mechanism of production of biogas. Described are factors which affect the production of biogas, its composition, properties, utilization and potential substrates. The next chapter deals with the technologies of biogas plants. The main part of the thesis is devoted to a proposal of a specific biogas plant in the Slovak Republic in the Novozámocký district. Included is the processing of design proposal, selection of components and proposal of the layout of biogas plant. The economic evaluation includes quantifying capital and operating costs and profits from the sale of electricity and compost.

Domestic heat pump
Veverka, Jakub ; Joch, Lukáš (referee) ; Pospíšil, Jiří (advisor)
The aim of the Bachelor's thesis is the ,,Heat pumps and house heating " . The thesis is divided into four main parts. The first part briefly describes the principle of operation and the types of heat pumps (The variants are water to water, air to water, earth to water), including the advantages and disadvantages of their use. Heat pumps are effective solutions to home and hot water heating. The part describes the heat transfer between the condenser and the heating pipes. The second part includes a proposal for using the specific heat pump, a brief description of the selected object and calculate the heat loss. The third part pays attention to calculating the energy performance of buildings. Economic evaluation of the selected system and financial returns are contained in the fourth part of this work.

Integral Transformations Using Vector Operators
Joch, Lukáš ; Štarha, Pavel (referee) ; Hoderová, Jana (advisor)
This Bachelor`s thesis is devoled to the vector operotrs. The operators plays the big role in the mathematical notation of different physical processes. The main aim od this paper is to show various vector operators and their properties. At the end are the integral theorems presented, concretely Gauss-Ostrogradsky theorem, Green`s theorem and Stokes`s theorem.

Fluid flow modeling in rotating engines
Joch, Lukáš ; Šen, Hugo (referee) ; Pospíšil, Jiří (advisor)
This thesis deals with modelling of flow in rotating engines. The introduction of the thesis discusses the principles of CFD modelling, such as mathematical flow model, numerical solution methods and model of turbulence. Next, the thesis is engaged in possibilities of a calculation model creation and its setting for a used model of steam turbine regulatory stage. The last part contains evaluation of calculation models and their comparison with different input parameters, regarding the fact that the aim is to get the most suitable setting for reaching the peak efficiency.

Project of wind power station
Kuljovský, Martin ; Joch, Lukáš (referee) ; Pospíšil, Jiří (advisor)
This Master’s thesis concerns a theme of wind power in Czech Republic. It gives a brief overview of wind turbines available at the European market, in the observed performance of range 50 kW with subsequent economic analysis for the locality. At the same time, it mentioned a probability distribution and the mathematical models needed for processing and evaluation of meteorological data. Nevertheless, the main part of this work is focused on the aerodynamic design of the blade of wind power plant for given location and it’s both with and without considering the possible losses.
