Flow in a bypass of a waterfeed valve
Waloszek, Jan ; Dohnal, Miloslav (referee) ; Juřena, Tomáš (advisor)
Fluid flow in pipes and fittings has a significant meaning in many sectors of industrial applications and thus it is important to reduce hydraulic ressistance in order to reduce pressure loses and ensure better efficiency of the system. In this thesis flow through two types of fitting is solved, using computer simulation. Empirical equations are used to verify results and to set the computer model right. This thesis formulates several conclusions in relation to k- turbulence model and accuracy of the results related to discretisation of the mesh.

CFD modelling of pipe flow mixing of liquids
Pavlíček, David ; Hájek, Jiří (referee) ; Juřena, Tomáš (advisor)
This work is focused on computational modelling of mixing fluids in pipeline with static mixers. Main objective is to analyze several selected static mixers in a particular industrial application, namely dosing of the aluminium sulphate solution in the clarification process for potable water treatment. The analysis focuses on the degree of mixedness and pressure loss of individual mixers. Further, the aim of this work is to process the search of available types of static mixers. The benefit of this work is at least an effort to motivate the reader to deeper understanding of the mixing fluids, especially by static mixers.
