Hydrokinetic swirl turbine
Fryčar, Michal ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
There has been a notable increase in interest in renewable energy harvesting over the past two decades. This has been accompanied by the emergence of new technologies and research, which are driving developments in this area forward. One of the sources is also kinetic energy of river streams and tidal currents. The aim of this thesis is to formulate fundamental equations for the utilisation of kinetic energy of water and to design a hydraulic model of a swirl turbine runner. A further aspect of this thesis is to verify the previously formulated equations in the computational modelling software Ansys CFX and to analyse the effect of the draft tube on the power output of the turbine.
Hydrokinetic turbines
Zrebný, Radim ; Zemanová, Lucie (referee) ; Rudolf, Pavel (advisor)
Bachelor thesis concerns about problematics of hydrokinetic turbines. First part briefly describes potential areas of utilization. Second chapter includes research of available technical solutions, its operation principles and characteristics, while the main distribution is according to the position of the axis of rotation. Following part describes basic principles of the flow theory and achievable limits of energy conversion. Last part deals with design of hydrokinetic turbine used in paper production. The design has been estimated via Blade Element Theory.
