Design of Pump-Inverter
Ferda, Tomáš ; Sládek, Josef (referee) ; Sovják, Richard (advisor)
Subject of this Bachelor’s Thesis is futuristic wall variable-frequency drive design, intended for pumps of up to 3kW power. The thesis deals with current products’ imperfections like plain shapes and/or insufficient display and controls ergonomy. Furthermore, the resulting design is enhanced with SD card data recording functionality and fulfils functional and engineering requirements, as well.

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.
