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.

Turbine Housing of Turbocharger VNT with Separated Pulses in Exhaust Manifold
Polášek, Jan ; Drápal, Lubomír (referee) ; Novotný, Pavel (advisor)
This master thesis deals with the design of the turbine housing of turbocharger VNT for supplying separated pressure pulses from the exhaust manifold. Subsequently, the work includes strength analysis of the designed turbine housing. The aim of the thesis is to create components for the supply of separate pressure pulses as close as possible to the turbine. Furthermore, the modification of the existing turbine housing and the assessment of the functionality of the VNT mechanism after this modification and strength analysis. The final aim of this thesis is the creation of 2D and 3D technical documentation of newly designed and modified parts.

Sensitivity analysis of flow through the vanes of the VNT mechanism
Čech, Martin ; Mrázek, Radim (referee) ; Vančura, Jan (advisor)
This diploma thesis analyzes the effects of various parameters of vane profile and position of VNT mechanism on the size of aerodynamic force which acts on the vanes and on the position of neutral axis of the vane. A CDF simulation was created to do this analysis, and the results of the simulation were evaluated. Thesis also deals with turbochargers in general and with other methods of their regulation.

Positive displacement pump design
Poprac, Martin ; Sluše, Jan (referee) ; Klas, Roman (advisor)
This bachelor work is about basic types of positive displacement pumps, focused on their design, advantages and disadvantages and their applications. In the second part of the work we are focused on the possibilities of reducing noise levels of some types of positive displacement pumps. The whole work consists of many pictures and diagrams for the better understanding.
