Modification of pump for turbine regime
Jahn, Jan ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
Hydraulic design of a hydrodynamic machine is designed to achieve a high value of energy transformation efficiency. Pumps and turbines have some different typical features in hydraulic design. With the aid of computational fluid dynamics, adjustments of the hydraulic parts of a standard centrifugal pump are assessed with the aim to increase hydraulic efficiency of the pump running as turbine. The impeller, volute casing and added draft tube are discussed.
Micro power plants for the use of residual gradients and flow
Komorová, Magdaléna ; Dráb, Aleš (referee) ; Žoužela, Michal (advisor)
The aim of the bachelor thesis is to bring information about where hydropower is going in the future in accordance to using residual gradients and flow. Also, bachelor thesis is looking into different types of turbines which can be used for residual gradients and flow, then how government is helping with funding of new and existing hydropower plants. The last part of thesis is analyzing new location for picohydropower plant and bringing three possible designs.
