Present Trends is Power Increasing of CI and SI Engines
Slovák, Jan ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is only the search character. In this thesis are described different types of engines, also are discussed the most common types of supercharging engines – by compressor and turbocharger. Along with them are showed less known methods of supercharging. At next chapter, thesis describes another possible methods of increasing of engine power like chiptuning etc. Last chapter is about near future and describes for example engine downsizing and hybrid cars.

Compressors for refrigeration equipment
Perejda, Michal ; Sekanina, Bohumil (referee) ; Štětina, Josef (advisor)
The work is devoted to the problematic of compressors for refrigeration equipment with a focus on industrial refrigeration and medium performance output requirements. Reader receives a basic overview of the construction, operating cycle, pressure and temperature process and the compressor performance control options of the three in engineering practice most common types of compressors: reciprocating, screw and scroll. It describes the basic elements and actions of the cooling circuit within the information range most important for understanding the compressor operating cycle. This work includes thermodynamic analysis of the reciprocating compressor working cycle and shows practical application of compression device in real operation. The goal of this work is to provide the reader with a description of the thermodynamic process in the compressor, a comprehensive and systematic overview of the types of compressors used in practice and compare their characteristics, advantages and disadvantages.

The redesign of the compressor for electromotor driving
Mikulka, Vít ; Venclík, Jiří (referee) ; Mazůrek, Ivan (advisor)
This bachelor thesis deals with redesign of the compressor for electromotor driving. First part focuses on the principle of compressors, their development and division. The next part describes a compressor MK 100 produced by Benda kompresory Ltd. company. The technical solution of its redesign for 2,2kW electromotor propulsion with maintaining a rotation speed mode of original Honda engine is explained in the last part. This compressor should be used in its redesign version at FME BUT in Brno.

Design of hybrid compressor for a 10PW laser
Kramer, Daniel ; Novák, Jakub ; Rus, Bedřich
The ELI beamlines facility wiil house a 10PW laser with ultrashort pulse duration. The laser damage threshold of the coating limits the minimum size of the last compression grating. Due to production restriction the last grating has to be tiled. The design was produced in order to minimize the total number of gratings in the compressor together with the spatial requirements.

Pasivní a aktivní metody řízení mezní vrstvy
Matějka, Milan ; Popelka, Lukáš
The paper deals with influence of the passive and active method of control on the flow field. It is well known fact that boundary layer separation has a fundamental effect on aircraft airfoil performance, compressors and turbines performance and other bodies, subject to study of internal and external aerodynamics. By the boundary layer control, it is possible to obtain both operational economy and extension of efficient operational region. Traditional methods of active boundary layer control are very complex and their application needs complex facilities. Modern methods based on the control by synthetic jets or plasma actuator are simpler, but their design has to be carried out at rather well experience and detailed knowledge about boundary layer and its interaction with the actuator.
