Induced siphonage of air into the flowing fluid.
Matlák, Jiří ; Opravil, Tomáš (referee) ; Svěrák, Tomáš (advisor)
The aim of this diploma thesis is to deepen the knowledge in the field of drain liquid from vessel with free surface due to the effluent jet with defined profile. Formation of complete suction vortex is taken place gradually depending on the starting conditions. In the diploma thesis basic relations in liquids considering whirl are described and the types of vortex are divided on the bases of circulation intensity. In the experimental part of diploma thesis the possibilities of liquid level prediction are searched for, where the whirl is formed depending on the size of effluent jet.

From tornado to hydraulic turbine
Jízdný, Martin ; Rinka, Lukáš (referee) ; Rudolf, Pavel (advisor)
This bachelor thesis deals with vortex motion and contains two main parts. The first part refers to the principles of creation and evolution of vortex motion in nature and in technological applications. In both of these fields it is possible to find positive and negative impacts of vortex motion which influence the world significantly. The second part of this bachelor thesis refers to an experiment which main goal was to verify some selected qualitites of vortex motion and to determine hypothesis based on measurements. The final part of the experiment deals with the different methods of making vortex motion visible in laboratory conditions.
