Experimental support for the development of specific integrated equipment
Hrbáček, Jiří ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
Regenerative heat exchangers are used in a wide range of industries and in the technical equipment of buildings. These heat exchangers play an important role in saving thermal energy and removing volatile organic compounds from flue gases. The theoretical part of the work deals with the division of regenerative exchangers into rotary and switching exchangers and the possibilities of their use. These types of heat exchangers are used in many applications, e.g. as a heat exchanger using waste heat to preheat the process gas (regeneration layer), or as catalysts to accelerate the reaction required to remove volatile organic compounds (catalytic layer), or as integrated equipment where both the regeneration layer and the catalytic layer. The aim of the diploma thesis is experimental support in the development of a computer program for the design of a specific integrated device. The program allows the calculation of the regeneration and catalytic bed, or both beds simultaneously, i.e. integrated equipment. The diploma thesis deals with the support of a mathematical model for the calculation of the regeneration bed. Pressure loss and heat transfer play an important role in the selection and subsequent calculation of a suitable bed. To calculate them, it is possible to find more available computational relationships that differ significantly in their accuracy. It is therefore necessary to select the most suitable ones for the computational model. The practical part of the work then deals with research, analysis, and assessment of the suitability of methods used to calculate pressure losses based on a comparison with the values measured on experimental equipment. Subsequently, the work deals with computational methods for determining the heat transfer coefficient of the packed bed. A significant part of the practical part deals with the modification of the experimental equipment for the verification of computational relations for the determination of heat transfer with measured data.

Economics of brownfields regeneration
Lukele, Petra Elly ; Pospíšilová,, Barbora (referee) ; Hromádka, Vít (referee) ; Špirková,, Daniela (referee) ; Korytárová, Jana (advisor)
The dissertation thesis focuses on the economic view of interventions in the extensive brownfields, ie uninhabited parts of cities, abandoned halls, buildings, industrial zones. It monitors the factors influencing their regeneration, deals with ecological and related financial issues. It examines the possibilities and ways of financing the recovery of these abandoned and unused areas. The work demonstrates the suitability of using the CBA method to determine the economic efficiency of brownfields regeneration projects. Whether the regeneration of brownfields is economically efficient, establishes a new indicator cef as the difference between the financial and economic profitability of the project. The work verifies the suitability of using the indicator on a research sample of 28 implemented brownfield regeneration projects. At the end of the thesis, the expected value of the social benefit of Monte Carlo is determined with the support of the Crystal Ball simulation software.

ZBROJOVKA FACTORY BRNO
Staffová, Eva ; Kristiánová,, Katarína (referee) ; Havliš, Karel (advisor)
Master thesis is developing a realistic strategy for regeneration and development of the post-industrial factory complex Zbrojovka Brno. Theme of thesis is to involve inaccessible area back into city life. Zbrojovka is not a typical brownfield area. Production was stopped in 2006 and the area is surprisingly full of life today, roughly 50 % of the land is used, leased objects are conserved and not decay. The main theme is transformation of the factory environment into a viable multi-functional urban area using the principles of sustainable urbanism. Compared to the developer plan this proposal maintain existing structures for further development. Zbrojovka factory is a place with unique atmosphere, with genius loci, which is worth preserving. The proposal uses the newly created public spaces as a catalyst for development and aims to attract “creative class“ that could Zbrojovka get into wider public awareness and attract the necessary investment for creation a lively part of the city with an industrial soul.
