Spiral case design for fountain turbine Katovice.
Čípa, Jiří ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
The diploma thesis should identify inconsistencies of the small hydraulic power plant Katovice. The fountain water turbine is now running in slower delivery because the original Francis high speed turbine achieved much smaller flow than a Kaplan type turbine. The aim of the thesis is a project of a spiral case and a distributor for the Kaplan turbine, which should work in higher flow and should be run in its optimum. This project will serve as a base for construction of distributor and spiral case for the small hydraulic power plant Katovice.

Spiral conveyor
Ploc, Jakub ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
Spiral screw conveyors, as conveyors without a traction element, use the effects of rotating spiral for transport. To ensure correct operation during upward transport, a prerequisite for functionality is created in this work. Furthermore, the selection of a suitable material for which the dried sewage sludge was selected is made. In the following parts, the design calculation, and the choice of the conveyor construction for the specified dimensional and performance parameters are performed. Finally, a strength check of the functional parts such as gutter deflection is performed. Part of the thesis is also drawing documentation, which is based on the text part.

Spiral conveyor
Žádník, Lubomír ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
The bachelor thesis deals with the design of a spiral conveyor. In the introduction is presented conveyor theory including its use and description of the basic parts. The following part describes the design calculation and selection of individual components from the specified parameters. Finally, a brief assessment is made. Everything is documented by the drawing file documentation, the list of items, and the assembly drawing.

Measurements of the stress in the turbine spiral casing using the strain gauges
Dokoupil, Pavel ; Pochylý, František (referee) ; Habán, Vladimír (advisor)
The Master‘s thesis is focused on measuring of the stress in the spiral case of water turbine using the strain gauges measurement. It contains the theoretical and the practical part. The theoretical part includes a description of theoretical background (basic mechanics, measurement and evaluation, strain gauges, pressure measurement, uncertainty of measurement). One of the chapters describes Water Power Plant Lipno nad Vltavou (history of power plant, issues and the history of measurement). The practical part contains a theoretical calculation of measurement uncertainty and measuring of stress on spiral case Francis turbine at Water Power Plant Lipno I (Unit TG2). Measurement was made before and after overhaul. There are described technical data of spiral cases, description of measurement, results of measuring of strain and stress including comparison with the pressure in spiral case and calculation of uncertainties of measurement.

Feasibility study of the pumped storage power station
Kratina, Jakub ; Duchan, David (referee) ; Dráb, Aleš (advisor)
Pumped storage power stations are an integral part of all power systems. At pre-sent, they represent perhaps the only option to accumulate more surplus electricity. It is also built as a proven regulatory element of the power system. The content of this bachelor thesis is a study of feasibility of the pumped storage power stationt (PVE Podlešín) in the Vaňov area. The introduction deals with the issue of pumped srorage power station. Then the design of a technical solution for the power plant construction follows. The main part of the study is the elaboration of drawing documentation and technical reports.

The architectural study of the church for the estate Lisen-Vinohrady, Brno
Havlík, Jiří ; Žalmanová, Petra (referee) ; Šindlar, Jiljí (advisor)
This diploma thesis deals with the issue of sacral space of Brno-Líšeň, where there is a request to build a church as a part the Salesian Center. Part of the problematics was the construction of the Parish house and the Community house as a part of the church mentioned above. The plot is situated at the site of the southern slope between Horáková and Molákova Street and in close proximity of the Salesi center. The project is conceived as a progressively graduating spiral rising from the mass of the community house to the sculpture of the cross at the tower of the church. Visually both building are separated from the north side but are partially connected thanks to the underground floor from the south side. The building of the community center shall be a three-story building. The design of the church itself is based on the centralization of space and due to progressive gradation to the center of the building, where all the events associated with the Christian year take place. The complex serves both as a place where the widespread society can fulfill their spiritual needs as well as a sanctuary of the Salesian community, where they can fulfill their mission.

Simulation of thermally activated foundation structures of buildings
Sliva, Matěj ; Adam, Pavel (referee) ; Šikula, Ondřej (advisor)
Diploma thesis deals with geothermal foundations. The aim of the thesis is to find optimal way of pipe winding for heat-carrying liquid in foundation piles. The problem is solved by CFD simulations in ANSYS Fluent. Determinative parameters like the pressure loss, heat fluxes and U-value in one pile circuit with two ways of pipe installations – Single coil, where reverse pipe is led in the middle of pile and Duplex Coil with reverse pipe in spiral shape are observed.

Optimalization of indirect resistance heating
Havránek, Miroslav ; Bok, Jaromír (referee) ; Lázničková, Ilona (advisor)
The indirect resistance heating is one of many ways of heating a melting charge. It is used in metallurgy, mostly for melting of soft metals. Its principle is a direct resistance heating in correspondence with the Joule´s law. The principle of indirect resistance heating is in generating of thermal energy in heating element and heat transferring this heat into the melting charge. The theoretical part of this Bachelor Work (the first three chapters) is focused to thermal energy generation and possibility of thermal transmittance. The fourth chapter is devoted to possibility of utilizing of the indirect heating in praxis. The simplest general design and calculation of a pot-type furnace for aluminium melting is done in the fifth chapter. There is a part in this chapter, which deals with the effectivity of the designed pot-type furnace and possibility of heating optimalization in case when indirect heating system is used. The input and calculated parameters of our designed furnace are summed up in the conclusion. There is also comparison of the designed furnace and a furnace readily available on the Czech market and stress on importance of optimalization of heating at indirect heating systems.
