Slip factor of the hydrodynamic pumps
Duda, Petr ; Archalous, Jakub (referee) ; Klas, Roman (advisor)
Bachelor thesis contains basic information about the hydrodynamic pumps. It describes the specific energy for an infinite number of very thin blade and following corrections to the finite number of blades. Part of this work is dedicated to all-weather resulting in Blade to blade channel and their effect on specific energy pump. There are illustrated by calculations of correction factors of individual authors and finally corrections are made on real three impeller wheels with a comparison of different methods.

The storage water plants problem appreciation
Archalous, Jakub ; Himr, Daniel (referee) ; Sloupenský, Zdeněk (advisor)
This bachelor’s thesis deals with the use of hydropower. It gives an overview of hydroelectric plants and describes mechanisms that convert water energy into electric energy. The most attention is paid to the principle and operation of pumped storage power plants and the machinery used there. Also the efficiency of the pumping cycle at Dlouhe Strane power plant is calculated.

Improvement of the suction capacity of the fire-engine pump
Archalous, Jakub ; Habán, Vladimír (referee) ; Pochylý, František (advisor)
This diploma thesis deals with reducing the time of sucking water into the rotating impeller of the centrifugal pump as used in firesport. The suction is carried out by the ejector, which is powered by combustion engine exhaust gases. A mathematical model was created, which shows the flow in the ejector. It was also used as a basis for the creation of a new ejector, which has an increased airflow when getting closer to atmospheric pressure.
