Methods for Kármán vortices suppression
Kukrle, Daniel ; Urban, Ondřej (referee) ; Rudolf, Pavel (advisor)
This bachelory thesis is considering a Kármán vorticies and their suppresion. The theoretical part describes principle of phenomenon origin and concepts connected with this topic. Following chapter deals with Kármán vortex street occurrence and danger. In the end of the first part there is an overview of phenomenon suppresion methods. Experiment applies selected suppresoin methods and proves their effectivness.

Active control of flow past a cylinder
Kukrle, Daniel ; Urban, Ondřej (referee) ; Rudolf, Pavel (advisor)
The diploma thesis is considering active flow control. At first part describes boundary layer separation and Kármán vortices formation. It also explains why it is important to control the flow, and the control is divided into basic categories. Then there are described known active flow control methods. Next part defines default problem with Kármán vortices formed behind a cylinder, analyzes flow and suggests useable flow control principles. In last part of the thesis are tested chosen flow control methods. At first there are verified open-loop methods, then closed-loop methods too.
