Radial turbine runner design with reduced moment of inertia
Votava, Ondřej ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
This master’s thesis deals with topological optimization of the impeller of a radial turbocharger turbine. It focuses on reducing the moment of inertia with unchanged aerodynamic properties. The optimization was carried out using CFD, thermal and structural analysis. The computational modeling was performed using the finite element analysis in ANSYS. The work proposes models of the impeller with the topological modification of the internal structure. Based on the values of moment of inertia, the stress and the strain the most suitable model was selected.

Technology for liquefaction gases and its use and distributing
Štěpánek, Jindřich ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This thesis deals with technologies for gas liquefaction and storage. The first section summarizes the development of liquefaction technology using expanders and throttling valves, followed by current technology. This is especially a rotary expanders. The storage technology is the above-ground storage of cryogenic tanks. The thesis includes proposals turbine wheels for liquefaction lines and included two proposals liquefaction cycles.
