Adjoint solver
Heinz, Pavel ; Kůrečka, Jan (referee) ; Moravec, Prokop (advisor)
This bachelor thesis deals with an analysis of selected settings of Adjoint solver in commercial software ANSYS Fluent 18.2. The first part of the thesis deals with the basics of hydrodynamics, especially the equations describing the behaviour of liquids. It also deals with the theoretical foundations of CFD simulation and shape optimization. Examples of simple shape optimization cases are presented in this thesis. The last part focuses on the analysis of selected settings of Adjoint solver. These settings are afterwards tested on specific hydraulic part for a purpose of a pressure loss reduction.

Utilization of wind energy for delivery of liquids
Červinková, Kateřina ; Moravec, Prokop (referee) ; Štigler, Jaroslav (advisor)
The aim of this bachelor is developing a deep search about uzilization of wind energy for delivery of luquids, which is transforming to mechanical or potential energy of the liquid. We can find history of wind pumps in this work. We can also read about pump overview, which are using for drive of wind energy, constructions and parameters. Finally they are advantages and disadvantages of transforming wind energy to mechanical energy or potential energy of the liquid against transforming to electrical energy.

Application of bionics for hydraulic turbine blade design
Kaprinay, Zoltán ; Moravec, Prokop (referee) ; Rudolf, Pavel (advisor)
This bachelor’s thesis deals with application of bionics for girl turbine blade design. In the first part the basic theoretical concepts of bionics are explained, and there are different inventions described which are inspired by nature from both past and present. The description of the principle and fiction of girl turbine is followed by designing the blade. Calculations are based on real data for the girl turbine. In the end of the work there is the 3D model of designed blade.

Mobile Water Treatment Plants
Trlica, Karel ; Moravec, Prokop (referee) ; Kárník, Jan (advisor)
This bachelor thesis deals with technologies of drinking water treatment. The focus is on comparison between mobile water treatment systems and ground water treatments. The first part of thesis is concerned with technology and construction of container water treatment system, while pointing out the benefits associated with its usage. The next part of thesis deals with ground water treatment system, analyzes its technologies and advantages. The thesis also assesses the performance differences between classic and container water treatment systems, while taking into account usage of mobile water treatment systems for specific conditions. The last part deals with specific water treatment systems, that is the container water treatment system CCW KU-1 and the water treatment system in Valašské Meziříčí. The thesis strives to explain both water treatment systems in detail. Overall evaluation and set of specific differences between the water treatment systems is included in the conclusion of the thesis.

Cavitation erosion testing
Sochorec, Rostislav ; Moravec, Prokop (referee) ; Rudolf, Pavel (advisor)
The thesis is a literature survey of three most common methods of accelerated tests of cavitation erosion. These are cavitation induced by changing flow velocity in relatively conventional high-speed water tunnels, vibratory method which uses ultrasound to produce cavitation, and jets of liquid impacting surface of materials. In order to understand them, there is also a brief general introduction to the issue of cavitation and most important factors which can have effect on cavitation tests results.

Numerical simulation of the flow in the components of the hydraulic circuit
Broža, Martin ; Moravec, Prokop (referee) ; Kozák, Jiří (advisor)
The bachelor thesis is focused on the analysis of the possibilities Autodesk Simulation CFD with simulation of flow in the hydraulic circuit elements. It is a commercial program applied in solving water flow in the selected elements of the hydraulic circuit, in elbow, sudden enlargement and 90 degree sharp elbow. The obtained results are compared with experimental results from laboratory and the results obtained by the ANSYS FLUENT.
