Turbocharger Regulating VNT Mechanism Load Simulation
Cetkovský, Martin ; Svída, David (referee) ; Vančura, Jan (advisor)
This diploma thesis deals with turbochargers with a focus on the ways of their regulation. The main subject is to design CFD simulation for a turbocharger with VNT mechanism at specific positions. Simulation is based on the turbocharger Garrett by Honeywell, for which measurement was realized. Finally torques acting on the vanes are evaluated from the simulation. The means of results improvement are considered at the end of the thesis.

Magnetic field effect on the flow character close to the surface
Buday, Jakub ; Šedivý, Dominik (referee) ; Fialová, Simona (advisor)
The aim of this bachelor´s thesis is to discribe basic properties of flow and magnetic field. Further characterize different applications of magnetic fluids. Also discribes the influence of magnetic field on some properties and behaviours of water. This thesis is comparing several conlusions of scientific articles, that are examining this subject. In the experiment the changes of three fluids were observed by the help of high speed camera. The contact angle of fluids before and after exposing to magnetic field is compared. In the second part of the experiment behavior of flowing drop through magnetic field is observed.

House water meters
Zvejška, Tomáš ; Tureček, Jan (referee) ; Ručka, Jan (advisor)
Bachelor´s thesis is focused to measurement accuracy of House water meters at very low flows. There are some errors during these flows. It´s not known what the values of these errors become, yet. The goal of my thesis is assessment of these errors. Results have been achieved through laboratory measurements.

Aerodynamics of road vehicles
Mužíková, Markéta ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis deals with aerodynamics of passenger cars, racing cars and trucks too. On the basic theoretical knowledge are connected various solutions used in the practice for a particular type of vehicle. To create a comprehensive overview of this issue is there described testing of vehicles in wind tunnels and numerical techniques with using computational systems.

Measurements of small flow in water service connections
Stehlíková, Veronika ; Ševčík, jiří (referee) ; Tuhovčák, Ladislav (advisor)
In the first part of this thesis the basic information about the losses of water and their reporting are described. There are presented the means and methods of reducing water losses and their suitability for use. Finally, general information about water meters are presented and the UFR device is briefly described. The second part of the thesis is devoted to testing water meter and UFR device on specific water connection in a family house. The thesis resulted in the author's general recommendations for owners and operators of water supply networks.
