Evaluation of the Financial Situation of the Company and Proposals for its Improvement
Kilhofová, Hana ; Hudec, Martin (referee) ; Žižlavský, Ondřej (advisor)
This bachelor thesis is focused on the evaluation of the financial situation of Broker Consulting, a.s. for the period 2015-2021. The evaluation will be made on the basis of financial analysis. Firstly, the objectives, methods and procedures of this thesis are defined. Then the thesis is divided into three parts. The first part contains the theoretical background, which is then applied to the analytical part. And the third part contains a detailed description of the proposals for improving the financial situation of the company.

Breakdowns caused by water hammer
Kuřátko, Jiří ; Hudec, Martin (referee) ; Himr, Daniel (advisor)
The goal of this bachelors thesis is to explain how water hammer occurs, listing often used protective devices that help mitigate this event and research of accidents caused by water hammer. The thesis deals with theoretical introduction into the topic, describing preservation laws for fluids, most common causes of water hammer and characteristics connected to this phenomenon. Then it mentions often used protective devices for both overpressure and negative pressure. Finally there are accidents caused by water hammer, some with unusual causes, which however still need to be taken into consideration when designing a pipeline.

Feasibility study pumped storage hydropower plant in a particular locality
Vaněk, Michal ; Štigler, Jaroslav (referee) ; Hudec, Martin (advisor)
Electric energy storage represents an area, which needs to be further developed in order to accommodate more installed capacity of wind and solar power plants in the electric grids. Pumped hydro energy storage still remains ahead of other storage technologies in terms of achievable storage capacity. However, environment protection which is one of the obstacles for further PHES development in Europe causes significant reduction of suitable sites. It is therefore useful to examine also those sites, which seem to be less favourable for PHES at the first glance. This thesis deals with a feasibility study of a PHES on place of a former graphite surface mine. The thesis includes computation of basic capacities, choice of a suitable machine arrangement and introduction into PHES feasibility issues in electric grids. Two possible solutions of a smaller PHES that differ in their capacities were suggested based on available materials about the site as well as on available materials from Francis pump turbine model research. In case of both solutions a binary machine set is used and the available capacities are in small tens of megawatts. However, there is a wide head variation at the site, which causes significant power variation. Concerning the feasibility of the PHES, it is very uncertain that the participation in the day-ahead electricity market, would provide enough revenue to cover operation and capital costs. A following economic analysis investigating the capital costs of this particular PHES would be beneficial, as well as more detailed design of the reservoirs.

Description unsteady operating conditions of siphon swirl turbine
Krejčiřík, Stanislav ; Habán, Vladimír (referee) ; Hudec, Martin (advisor)
The master´s thesis focuses on the behavior of the siphon turbine during unsteady flow. There are two possible conditions. The first condition involves commissioning the turbine. In this situation turbine works like a pump. In the second case, it includes shutting down the turbine by aerating the siphon and thereby breaking the water column. This thesis deals with the second case, where the results of the experiment and the mathematical model are compared.

Adaptation of the water mill
Dobšáková, Lenka ; Uttendorfský, Petr (referee) ; Hudec, Martin (advisor)
This bachelor’s thesis is about adaptation of the water mill Cacovice. The first part is a description of the history of water mills and mill history in Cacovice. The second part deals with small hydroelectric power station, their functions and distribution. The third part describes the technical part of the small hydroelectric power station Cacovice and the fourth part is a proposal for a new Kaplan turbine, which could replace the existing Francis turbine.

Innovation of the laboratory stand Water jet
Šimůnek, Petr ; Rudolf, Pavel (referee) ; Hudec, Martin (advisor)
The subject of this bachelor's thesis is the design of a new experimental device for measuring the force of a water jet on various shaped surfaces. The first part of the work is focused on the theory around the task. The second part deals with the parts of the device. And in the third part is carried out exemplary calculation.
