Particle separation from fluid flow
Fejta, Vojtěch ; Urban, Ondřej (referee) ; Štigler, Jaroslav (advisor)
This bachelor thesis deals with the particle separation from fluid flow. The aim of this thesis is to get acquainted with the already existing methods of separation, to study their principles and to describe devices designed for particle separation. The thesis is divided into two main units, the first explains the individual methods of separation, the second describes the specific particle separators, their advantages and disadvantages. The final part of the thesis is devoted to the design of another approach to separation.

Fluid-structure interaction between blood and dissipating artery wall
Fara, Jakub ; Tůma, Karel (advisor) ; Bodnár, Tomáš (referee)
In this thesis we introduce a new fluid-structure interaction model in the Eulerian description. This model is developed for blood flow in viscoelastic artery. For the fluid part a non-Newtonian model Oldroyd-B is used and for the structure part Kelvin-Voigt model is employed. Kelvin-Voigt model will be reached by a limiting process of the Oldroyd-B model. Interface between these two materials is guaranteed by conservative level-set method. Numerical tests of this model is performed by finite element method. This model is used for a simulation of two problems: a two dimensional channel with viscoelastic walls and pulsating inflow and Turek-Hron FSI benchmark. 1

Implementace vypařovacího systému pro depozice tenkých vrstev
CIFREUND, David
This thesis focuses on gas dispensing for PECVD proceses in low temperature plasma. Key to succesful depositions is an accurate and stable flow rate of precursor to reactor, where discharges are used for depositions of thin films. Liquid can be also an admixture of the precursor, but it has to be mixed with the carrier gas and finaly evaporated. For this purpose was chosen CEM evaporating system from Bronkhorst High-Tech B.V., which is composed of gas mass flow controller, liquid mass flow controller, evaporating device and control unit. Main goal of this thesis is to implement evaporating system to plasma chemical reactor, calibrate it and do measuring tests.
