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.

Computational simulation of air flow in a gas burner
Waloszek, Jan ; Rudolf, Pavel (referee) ; Vondál, Jiří (advisor)
This work is focused on computational modelling of a flow in a burner. The main objective is to provide a complex comparison of the results obtained through several approaches to modeling, on different computational grids and also using different turbulence models. Experimental measurement data are used for validation. Numerically obtained data are compared to each other and to experimental data. The method of Proper-Orthogonal Decomposition is also applied on the calculated data. The greatest benefit of this work is providing a wider view on the swirling flow modeling in burners and the results obtained here will help to better understand the behavior of stated models for tasks of this kind and their potential for modelling combustion in furnaces.
