Cavitation in microfluidic orifice
Bohunský, Tomáš ; Burda, Radim (referee) ; Rudolf, Pavel (advisor)
This diploma thesis deals with cavitation flow in the microscale, which remains an area with a lack of sufficient description of this phenomenon. At the same time, microfluidics is a field experiencing a dramatic rise in numerous biochemical applications, which underlines the relevance of researches of this type. In theoretical part of the thesis, cavitation was described in detail. In the practical part, a microfluidic device with a cavitation orifice was designed and manufactured. The ANSYS program was used for this design. An experiment was performed with the designed microchip, the aim of which was to observe a cavitating flow on the orifice. This measurement took place at the microfluidic laboratory at Victor Kaplan Department of Fluid Engineering. Due to the failure of the experiment, a CFD model of two-phase cavitation flow was built. The conclusions of the thesis were compiled from the findings of measurement and the results of modeling.

Microfluidic circuit
Zeman, Radek ; Zemanová, Lucie (referee) ; Rudolf, Pavel (advisor)
Microfluidics is a science dealing with flow of a very small amounts of fluids and is mainly connected with medicine and biochemistry. One of a main problem, which this science is facing, is a difficult mixing of fluids due to occurrence of laminar flows. This bachelor thesis contains a design of a microfluidic circuit with Staggered herringbone microfluidic mixer and subsequent implementation of the experiment according to the performed design.
