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.

Slip factor of the hydrodynamic pumps
Chromek, Lukáš ; Himr, Daniel (referee) ; Klas, Roman (advisor)
This bachelor thesis deals with the initial draft of an impeller wheel, determination of its specific energy that has a pump with infinite number of impeller blades and following correction to real specific energy of an impeller wheel pump with finite number of blades. The correction will be performed using different methods by various authors and some of the methods will also be compared during the calculation of specific energy and discharge head of pump of several real impeller wheels. Then the thesis goes on to deal with some of the effects arising from the flow of fluid in the impeller wheel that often have negative influence on above-mentioned specific energy. At the end of the thesis, there will be brief abstract on problems of the correction, simulation, and analysis of flow in a blade channel using CFD software.
