Flow visualization
Vavrla, Zdenek ; Šperka, Oldřich (referee) ; Rudolf, Pavel (advisor)
This bachelor´s thesis deals with fluid flow visualization methods in the air and water. First brief characteristic of the basic concepts of fluid flow is described, such as streamline, laminar and turbulent flow. The described visualization methods are divided into certain types and are used for fluid or gas. These methods provide a qualitative view of the flow and create the overview of the characteristics of gas or liquid flow. Some of these methods are simple and some are more complex. Finally, a simple experiment of liquids flow visualization is described by very powerful laser pointer.

Vortex ring
Zaremba, Matouš ; Šperka, Oldřich (referee) ; Rudolf, Pavel (advisor)
The aim is to design equipment for the production of a vortex ring. The work deals with design of equipment, manufacturing and experimental verification of the functionality of some experiments with vortex rings. The work also includes a theoretical part which mathematically describes the motion of the vortex ring.

Positive displacement pump design
Klapka, Petr ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
This thesis gives an overview of the structure of hydrostatic pumps. First, there is shown the integration of the hydrostatic pumps between other hydraulic machines and then there are described the fundamental relationships and characteristics. The main objective of this work is to make a basic list of species distribution and the classical hydrostatic pumps. For each type, while mentioning his principle, his description of the main members is also highlighted some of their advantages and disadvantages.

Pump design
Šmíd, Pavel ; Šperka, Oldřich (referee) ; Klas, Roman (advisor)
The aim of this labour is to analyze the structural design of pumps used in the present time. First, we focus on the distribution of pumps by type of energy conversion, and there are hydrostatic and hydrodynamic. Will further comparison of these types, and enter the region of their optimal application under specific speed. This labour will focus only on the hydrostatic pumps when we will do an analysis of design performance of the individual pumps and we'll give the advantages and disadvantages of the specific pumps. We shouldn´t forget the basic technical parameters and individual areas of practical use these given types. At the end of the labour will be processed the basic equations and the ideal characteristics of pumps.
