Low specific speed pump working in turbine mode
Bezdíček, Jiří ; Moravec, Prokop (referee) ; Štefan, David (advisor)
The use of the pump in turbine mode is an evolving area. For this reason, research of less standard pumps from the edges of the specific speed spectrum is suitable for this purpose. This diploma thesis was focused on the influence of splitter blades on the exclusively turbine mode of a low specific speed pump. CFD calculations of the pump were performed, considering the sidewall gaps between the stator and the rotor. CFD served not only to obtain turbine characteristics but also to describe the flow and analysis of other phenomena, such as volumetric efficiency or hydraulic forces.

The tooth pump in the turbine regime
Tyburec, Adam ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
The objective of this diploma study is to develop and secure production of gear turbine with very low specific speed in comparison with conventional turbines. The first part of the work deals with already performed research of similar hydrostatic turbines. It is followed by construction design, including complete drawing documentation. The production of the prototype is secured by an external company. Finally, an experimental measurement of the characteristics of the designed turbine is performed in the laboratories of Fluid Engineering.
