Modeling two-phase bubble flow in microfluidics
Stehlík, Martin ; Kozák, Jiří (referee) ; Rudolf, Pavel (advisor)
The goal of submitted thesis is to perform a computer simulation of bubble creation in T-channel. In the first section of the paper, the theoretical applications of microfluidic bubble, micromachines and droplet formation are described. In the second part of the text, author uses cross flowing method for simulation od bubble creation. Furthermore, several settings in computer simulation software Fluent are mentioned. In addition, the influence of velocity at the T-channel inlet on surface tension and on bubble length is presented.

Design of microfluidic mixer
Abrahám, Martin ; Fialová, Simona (referee) ; Rudolf, Pavel (advisor)
Microfluidic devices are more frequently being used in medicine as they operate with small amounts of test samples, such as blood or reagent chemicals. To work with such substances, effective mixing of the solution is usually required, which emerged as the most challenging problem in microfluidic systems. Due to the minor dimensions of the devices only laminar flow occurs, thus the turbulent eddies do not contribute to the mixing, but only the molecular diffusivity.
