Propelling nozzles of turbofan engines
Milko, Michal ; Janhuba, Luboš (referee) ; Šplíchal, Miroslav (advisor)
The thesis describes the work principle of propelling nozzles of two-stream engine in terms of thermodynamics and also describes common design solutions which are used at most types of turbofan engines. Thesis also describes the advantages and disadvantages of each adjustments and trends in development of propelling nozzles.

Tesla Bladeless Turbine
Lokaj, Jakub ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
The diploma thesis describes design of bladeless machine known as a Tesla turbine. The work is divided into theoretical part, practical part involving the design and experimental measurements of made bladeless turbine and a final assessment of thesis. The theoretical part deals with the basic design features of bladeless machines and their design modifications and flow in the nozzles. Furthermore there is a dedicated part of the dynamics of working fluid in the rotor of bladeless turbine represented by CFD modeling. The practical part includes the design and construction of parts of the turbine on a preliminary calculation using an analytical model of the flow in the turbine. The designed turbine components were checked for operational safety with structural calculations of shaft and disk impeller. The thesis was also performed experimental measuring of parameters of designed bladeless turbine. Measured values were compared with the analytical model which predicted turbine efficiency. In conclusion, besides to assessment, thesis also outlines possible proposals for further improvements of constructed bladeless turbine.

Using Computer Aided Engineering for analyse the detector
Vyroubal, Petr ; Polsterová, Helena (referee) ; Maxa, Jiří (advisor)
This master's thesis deals with influence of the shape comparison of convergent and Laval nozzles in the secondary electron detector shutters to the resulting pressure and gas flow in the secondary electron detector for environmental scaning electron mictoscope. To the detector analysis are used Computer Aided Engineering systems CAD and CAE, SolidWorks and SolidWorks Flow Simulation.
