Supercharger for internal combustion engines
Bílek, Vojtěch ; Svída, David (referee) ; Píštěk, Václav (advisor)
This bachelor’s thesis dealing with supercharges for combustion engines is focused on introducing the principles of how superchargers actually function in the combustion engines. The introduction briefly explains the topic to the reader and outlines the structure of the thesis. The following part involves a brief historical excursion of supercharging. Explanation of thermodynamic circuits in combustion engines follows. The main part of the thesis describes the individual types of supercharging, while the conclusion stresses the most common malfunctions and gives an overview of latest technologies development, since these will allow motor vehicles to achieve better dynamics and a more ecological operation.

Vyšetřování charakteristik ventilátoru použitého jako zdroj vzduchu v experimentálním zařízení pro zkoumání šroubovicových nestabilit v proudících tekutinách
Tesař, Václav ; Kukačka, Libor ; Kellnerová, Radka
For investigations of aerodynamic properties of helical instabilities in flowing fluids, an experimental rig is currently built. It is intended on the one hand for visualisations of acoustically excited helical structures and on the other hand for model experiments with flows of cyclonal character. As the universal air source for both purposes, a blower is used for which no loading characteristics were available - and which, at any rate, is to be operated in some of the regimes at very low Reynolds numbers where one has to expect deviation from characteristics obtained under standard conditions. The authors investigated the blower loading characteristics experimentally and used this opportunity to apply and test practical validity of the general ideas about universal representation of characteristics and criterial similarity parameters of turbomachines, published considerable time ago but seemingly little known and used.
