High Efficiency Gas Turbine Recuperator
Hejčík, Jiří ; Lábaj,, Ján (referee) ; Polanský, Jiří (referee) ; Jegla, Zdeněk (referee) ; Jícha, Miroslav (advisor)
This thesis deals with the high efficiency gas turbine recuperator design and its production methods. First part of the work presents an analysis of basic constructions and materials used for present recuperators. The requirements on the recuperator for a low emission gas turbine power source are then specified and the recuperator is designed according to the available literature sources. The quality of the heat transfer surface is examined by CFD modeling using the commercial CFD code Star-CD. The second part deals with the recuperator manufacturing and experimental validation of the designed recuperator performance. This section describes ways to build the recuperator matrix, technologies available to assemble the recuperator and methodology of measurements. Experimental results are presented including a discussion of the uncertainties of determining individual variables. Finally the engineering equations are found based on the experimental data obtained, that can be employed to design the recuperator.

Optimalization and calculation of transition duct design
Havlíček, Tomáš ; Náhlík, Luboš (referee) ; Paloušek, David (advisor)
The goal of this thesis is to create a methodic and a system, which would involve customized computing and consequent design of the transition duct using input and applied data effectively and would achieve optimized set of parameters. The methodic described in the thesis is applied on transition duct within air main ducting between the filter and gas turbine. Transition duct is a huge mounted assembly consisting of welded parts. NX 5 application was chosen as system environment of the thesis. Master model is a root for both design model and computing model. Weight and material optimization is a desired result which will serve as basis for designing. It is not the goal of this thesis to create one perfect computation model BUT to create a methodic, which would be manageable by any designer equipped by basic knowledge of engineering.

Gas turbine closed cycle
Kovář, Radim ; Šen, Hugo (referee) ; Fiedler, Jan (advisor)
Diploma thesis deals with the gas turbine closed cycle. The first part concerns the maximum of theoretical efficiency and practical excutable efficiency for the cycles without regeneration, cycles with regeneration and cycles with regeneration with split compression. The second part concerns the optimalization of the recuperator towards the speed of gas flow in the pipes of the recuperator. The third part includes weight and size design of two kinds of recuperators for different levels of regeneration.
