Modelling the Oil Lubrication System of Turbocharger
Breckl, Lukáš ; Hliník, Juraj (referee) ; Novotný, Pavel (advisor)
The diploma thesis contains a research part focused on turbocharger construction, engine lubrication system and turbocharger, basic physical properties of lubricating oils and hydrodynamics. The purpose of this thesis is to create analytical and CFD computational model of turbocharger lubrication system. Output pressures and the loss of specific energy are determined.

Shape optimization of hydraulic turbine diffuser
Hliník, Juraj ; Popela, Pavel (referee) ; Rudolf, Pavel (advisor)
This bachelor thesis deals with mathematical optimization focusing on the shape optimization in fluid mechanics with help of a CFD software. More specifically, it comprises the shape optimization of a swirl turbine draft tube with a specified rotational symmetry and the whole process is realised with Nelder-Mead and BFGS algorithms. The main object was to maximalize the pressure coeficient, with help of the algorithms which were implemented in Matlab software.

Piston and liner wear
Blach, Jiří ; Hliník, Juraj (referee) ; Dlugoš, Jozef (advisor)
The aim of the presented bachelor’s thesis is to create a piston skirt wear computational tool which will be added to a computational model of piston dynamics. The background research of the work describes particular modes of wear and previous work including this topic. Afterwards the application of Archard’s wear equation on an examined system is shown with two important input parameters specified in greater detail. Tool is added to a user-written subroutine through which three simulations of an engine operation are performed. Eventually, future optimizations are suggested.
