Formula Student Turbocharger Lubrigation
Novotný, Tomáš ; Špičák, Milan (referee) ; Janoušek, Michal (advisor)
This bachelor thesis deals with turbocharger´s bearing housing lubrication. The first part is focused on searches about this topic, it describes parts of lubrication system and ways of oil distribution. The next part deals with design of independent lubrication system for Formula student car´s turbocharger, in particular design of gerotor pump and it´s pressure regulator.

Windlass
Martinek, Jan ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
Windlass is a lifting device widely used in the building industry for lifting or laying building material or other material. This thesis consists of two parts. The theoretical part focuses on existing solutions of different windlass types and contains also a general overview of windlass producers. This part is also concerned with strength and functional calculations of the device and designs individual components of the device. The other part of this thesis is the construction part which is focused on drawings of the overal equipment assembly, contains the list of components and selected production drawings.

Turbocharger Rotors Using Gas Bearings
Sembol, Tomáš ; Dlugoš, Jozef (referee) ; Novotný, Pavel (advisor)
This bachelor's thesis is a research project focused on turbocharger rotors using gas bearings. The work is devided into seven chapters. The first chapter is brief summary of history of development of turbochargers for combustion engines. Basic working principles of turbocharger are descriped in second chapter. Third chapter is about the construction of individual parts, as well as about the turbocharger as a whole. The fourth part is devoted to the design, technical solutions and applications of aerodynamic bearings. The fifth and sixth chapter explains some of computational and experimental method. The final chapter lists required structural modifications of existing turbochargers.

Numerical simulation of oil flow in bearing housing
Zogata, Filip ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This thesis is concerned with the development of a computational model of the bearing node, since in the development of a synchronous generator, great emphasis is placed on the proper design of the bearing node, as this complex component has a direct effect on the overall efficiency of the generator. A large number of engineering experiments need to be used to test on the physical model, but it is also necessary to test using the numerical model, as the production of the prototype itself for testing is very costly, and therefore it is advisable to verify the prototype itself before production by a series of numerical simulations. Another important feature is the possibility to investigate even unfavourable or even extreme conditions, which are already very difficult, sometimes impossible, to test physically in the laboratory, and these numerical simulations can be divided according to several parameters, but in the field of bearing nodes we mainly encounter structural, dynamic, temperature or flow problems. This thesis in particular is focused on establishing a basic overview of computational fluid dynamics in the oil flow domain, while this knowledge is used in practice, as another objective is to develop a numerical model of lubrication of the aforementioned bearing node. However, this is a very complex problem, and therefore a study is first carried out to investigate the key components, and only by gradually adding different elements is the numerical model created in the Particleworks software environment, while a sensitivity study is carried out focusing on particle size. Subsequently, the individual partial results are summarized in the conclusion of this paper.
