Analyses of the Compressed Air Energy Storage proces in Ansys Fluent system
Hájková, Věra ; Šabacká, Pavla (referee) ; Maxa, Jiří (advisor)
This bachelor thesis discusses different types of energy storage in the introduction. It describes the different technologies, their functions, advantages and disadvantages. It compares them on the basis of the ESOI ratio, which is the ratio of energy stored on invested. The main type of energy storage covered in the term paper is compressed air energy storage. The thesis describes the principle of a method of energy storage as well the companies and projects that are working on or using this technology. Furthermore, the issue of heat energy loss during air compression is outlined, which leads to a significant reduction in efficiency. The last part of the thesis is a practical part, which uses a model example to show the temperature and pressure evolution during the pumping of air into the storage tank.

Solid Fuel Boilers
Skočík, Lukáš ; Špiláček, Michal (referee) ; Baláš, Marek (advisor)
This thesis is engaged in heating of the family house by solid fuel boilers, both fossil fuels and the modern forms of biomass. The first section describes and explains the properties, composition and important characteristic quantities of these fuels. It also discusses the classification, description and processing options of solid fossil fuels and biomass.Then they are briefly described the principles of combustion boilers for these fuels along with their properties, advantages and disadvantages. The last section focuses on the selection of a suitable boiler fuel for the selected reference house.

Odezva kalorimetru Tilecal na miony
Javůrek, Tomáš ; Davídek, Tomáš (advisor) ; Dolejší, Jiří (referee)
Title: Tile Calorimeter response to muons Author: Tomas Javurek Department: Institute of Particle and Nuclear Physics Supervisor: RNDr. Tomas Davidek, Ph.D. Supervisors e-mail address: davidek@ipnp.troja.mff.cuni.cz Abstract: The aim of present work is investigation of Tile calorimeter (subde- tector of ATLAS experiment) response to muons. Muons can help to monitor spatial non-linearities in this hadronic detector. Graphs of unifromities are used for these purposes i.e. dependence of dE/dx (deposited energy per unit length) on azimuthal angle φ and polar angle θ which is represented by pseu- dorapidity η. Finally the dependence of dE/dx on energy was also studied. Keywords: TileCal, muon, uniformity, energy loss
