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.

Active aerodynamic components of road vehicles
Stiborová, Dana ; Hejtmánek, Petr (referee) ; Vančura, Jan (advisor)
In this diploma thesis active aerodynamic components are designed, specifically brake cooling duct and active automotive wing. Cooling duct prototype and also active regulation controlling electronics including the software were created. Road test was performed to measure the duct parameters. Construction design and the active regulation function of the automotive wing were created. The influence of the wing on aerodynamic characteristics of the car was determined.
