Design of a cooling circuit for heat removal from a steam turbine condenser
Susna, David ; Pospíšil, Jiří (referee) ; Kracík, Petr (advisor)
This thesis deals with the problems of wounding of low potential transferred from steam turbine condenser. First, in the theoretical part variations of steam condenser design are described. Then there is a description of variations of cooling cycles and possibilities of their operation range. In second part of the thesis there are two common cooler options chosen. Those are wet cooling tower with natural draft and dry chiller with forced draft. Two types of cooling liquid are chosen to be used for dry cooling. These are water and the other one is 50 % mixture of water and propylene glycol. Based on the calculation results of both cooling cycle variations appropriate pumps are chosen, fan for forced convection respectively. Parts of the thesis are also projection drawings for both calculated variations.

The Municipal Baths
Ruščák, Matej ; Havlíček, Tomáš (referee) ; Nový, Vítězslav (advisor)
Project tries to answer the question what place does municipal baths have in contemporary society on a specific case of baths with relationship to river and surrounding neighbourhood. This baths are a place for recreation and socialization with accent on social apects. Baths build on proven experience from local baths tradition (european/roman) as well as exotic (arabic, asian). In the same time it articulates them in contemporary language and adjusts them to conditions of contemporary society.

Utilization of physico-chemical analysis in study on cellular water
Matejčíková, Eva ; Obruča, Stanislav (referee) ; Sedláček, Petr (advisor)
The bachelor´s thesis deals with the study of methods, available at the Faculty of Chemistry at Brno University of Technology, that can be used to determine physical and chemical properties of cell water. The main task of this work was to specify which of these methods are suitable to determine physical and chemical properties of water in the cell and the properties of water occuring close to the cell surface. Based on the background research the series of experiments were proposed and implemented. Subsequently, this work deals with the optimisation of methods that were defined as the applicable techniques to determine the properties of cell water.

Renewable energy sources in CR
Kozumplík, Ondřej ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech republic. It appears here the principal, use, potential and advantages and disadvantages of each type of renewable resources - water, wind and biomass. Then the use of solar energy for photovoltaic conversion to electrical energy is described in detail. At the end of this study is described one of the many recently build photovoltaic power stations in the South Moravia territory, the solar power station in Bzenec.

Thermal baths Yverdon, five senses in architecture
Pospíšil, Tomáš ; Uřídilová, Marcela (referee) ; Koleček, Ivan (advisor)
Peace in the shadow of the trees. A spring coming up from depths. The spa park is an island at the edge of the town. It is the highest value of its surroundings. That is why I place the volume of the spa on the side of the park along the road. There is a promenade connecting the constituent elements of the building. Full, heavy masses alternate with airy and bright ones. The park grows through the buildings, and in this way the spa and the park become closely intertwined. The interweaving of the built and the natural as the central theme of the project.

Trasfer Heat Analysis in Steam Generators in blocks of VVER 440
Roupec, Petr ; Pulec, Jiří (referee) ; Šen, Hugo (advisor)
The aim of this thesis is to analyze the heat transfer in steam generator of blocks in the nuclear power plant VVER 440. The steam generator represents the border between the primary and the secondary circuit. The heat is carried from a warm water from reactor to a cold water. The steam arises after the heat transfer and drives the steam turbine. An important quantity which represents the heat transfer is a heat transfer factor. This thesis is divided into theoretical and a practical part. In the theoretical part is mentioned a principle of the steam generator and the theoretical calculation of the heat transfer factor, which comes first of all from the character of the streaming in the steam generator. The practical part brings a comparison of the heat transfer factor calculated from data measured after the start of the third block of EDU in 1986, with the heat transfer factor which comes from the measurement after the power-increase for 105 % of nominal power of the same block in 2009. Further is shown the prediction of the heat transfer factor for next power-increase and the following service is shown too.

Magnetic field effect on the flow character close to the surface
Buday, Jakub ; Šedivý, Dominik (referee) ; Fialová, Simona (advisor)
The aim of this bachelor´s thesis is to discribe basic properties of flow and magnetic field. Further characterize different applications of magnetic fluids. Also discribes the influence of magnetic field on some properties and behaviours of water. This thesis is comparing several conlusions of scientific articles, that are examining this subject. In the experiment the changes of three fluids were observed by the help of high speed camera. The contact angle of fluids before and after exposing to magnetic field is compared. In the second part of the experiment behavior of flowing drop through magnetic field is observed.
