Development of turbochargers
Zogata, Filip ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This bachelor thesis deals with the development cycle of a turbocharger. When we are developing complex components, which completely include the turbocharger, it is necessary to use a number of technical experiments, both testing on a physical model and using computer programs. The aim of this work is to create a basic overview of the requirements for the development of turbochargers, then to approach the use of numerical simulations and testing at gas stations. This work also mentions current trends in this industry based on published studies from recent years. In the final part, the calculation of the modal analysis of the turbocharger is performed using two approaches.

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.
