Osmotic power plants
Šikula, František ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
The main purpose of this bachelor thesis is a theoretical description and an analysis of osmotic plants, mainly their suitability for being used as an alternative source for energy making. In the first part of this thesis are explained elementary principles of converting osmotic power to energy. In the next part are presented main characteristic features of an osmotic power plant. This section consist of description of its potential location, of water pre-treatment and of membranes units. The last section of this thesis consists of a case study, which analyses a potential osmotic power plant located in Scotland. In this case study are summarized all assumed approximate costs of this power plant. In the conclusion was proved that nowadays osmotic power plants are not financially favorable.

Alternative Energy Resources for Family House
Němec, David ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis is focused at an issue of thermal energy supply for family houses from renewable resources. The aim of this thesis is to provide a summary of possible thermal energy supplies from renewable resources (solar collectors, heat pumps). After that follows a draft and economic evaluation of these systems for individual sources of thermal energy. In introductory section a solar energy is described. It is a significant part of renewable energy. This part is followed by review with description, composition and principle of individual types of solar collectors and heat pumps. Next part is focused on draft of these systems. Conclusion is then dedicated to energy evaluation of individual designed systems.

Ranque-Hilsh vortex tube
Obrlík, Jan ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
Ranque-Hilsch vortex tube is thermally-fluid device in which there is a conversion of the pressure energy of the incoming fluid stream to heat energy of two exiting streams without any mechanical parts. The first part of this paper deal with the basic distribution, applications and principle of the vortex tube, which is not fully understood. In the second part there has been carried out a search about performed experimental measurements. Based on this research is designed optimized experiment. The last part of work is the evaluation of the measurement, which was carried out on an industrial vortex tube.

Shale gas extraction
Podhorský, Jakub ; Brázdil, Marian (referee) ; Šnajdárek, Ladislav (advisor)
This bachelor’s thesis on Shale gas extraction describes extraction and world shale gas resources. At the beginning it provides introduction to the terms of geology and overview of historical evolution of extraction and crucial technologies that are currently used in extraction. Shale gas exploration and extraction development is briefly mentioned. Horizontal drilling and hydraulic fracturing is then further described and also summary of the equipment is provided. Potential environmental risks associated with extraction or hydraulic fracturing itself are described. Subsequently world shale gas resources and potential extraction places are described. World technically recoverable resources are estimated at 7245 Tcf. Shale gas commercial production is currently underway in the United States, Canada and China.

Design of a unit for utilization of waste heat from a computing system
Valachovič, Filip ; Brázdil, Marian (referee) ; Chýlek, Radomír (advisor)
Global warming and the associated high energy costs are considered as the main problems at presents. As a result, there is an interest in reusing waste energy. This bachelor thesis is devoted to the design and assessment of the potential use of waste heat generated by the systems for the mining cryptocurrencies. The first part of the work deals with the process of mining cryptocurrencies as a whole and their energy consumption. The work, among other things, deals with the possibilities of cooling and subsequent recovery of waste heat from these systems. Part of the work is a theoretical design of a unit for waste heat recovery from mining rigs, considering immersion cooling with the resulting economic balance.

Methods of Measuring of Particulate Matter Emissions
Bašta, Tomáš ; Brázdil, Marian (referee) ; Lisý, Martin (advisor)
This thesis deals with the methods applied for measuring the solid pollutants in the flue gases. It is divided into two main parts. The first part deals with the general problem of solid pollutants, methods of measurement and emission limits. The second part is devoted to the experimental measurements and determination of the mass concentration of solid pollutants in the flue gases of the combustion unit for solid fuels GEMOS 110. It shows the measurement procedure, necessary calculations and evaluations.

Surface Condenser
Janíček, Martin ; Brázdil, Marian (referee) ; Fiedler, Jan (advisor)
This diploma thesis deals with design of surface condensers with axial steam inlet which are widely used in the energy industry. In the practical part, hydraulic and heat calculation, dump-tube design and calculation of by-pass were made to design surface condenser with axial steam inlet. Two types of surface condenser were designed in order to compare impact of two different heat transfer tube materials. Stainless steel and copper-nickel alloy were used for condenser calculation. Stainless steel and copper-nickel alloy condensers were compared in order to weight calculation and condenser price estimation.

Comparing invest to save heating
Ingr, Adam ; Brázdil, Marian (referee) ; Baláš, Marek (advisor)
This Bachelor’s Thesis is aimed at reducing the costs associated with the heating of family houses. A model house was selected for which its heat losses, annual heat consumption and heating costs were calculated. Then, an inventory of possible measures to improve energy performance of the model house was produced. Subsequently, some proposals were selected for which an economic assessment was made.
