Computational modeling of flow field with separation
 Šamša, Petr ; Elcner, Jakub (referee) ; Jícha, Miroslav (advisor)
This diploma thesis is considering with computational modeling of flow field with separation. In the first part it contains theoretical bases of flow field computational modeling with RANS models equations and wall treatment modeling approaches included. There is also flow separation in asymmetric plane diffuser modeling described in the thesis where the most suitable turbulent model and the proper mesh parameters for the successful flow separation modeling should be chosen. Next the chosen turbulent model and parameters verification via flow separation modeling on the asymmetric 3D diffuser mesh. That analysis should ensure if the chosen turbulent model is applicable also for engineering problems. At the end of the thesis there is evaluation if the setup chosen in the thesis is suitable to apply in any practical aeroacoustics problem modeling.

Plan curved pedestrian bridge
 Lachová, Alžběta ; Jurík,, Michal (referee) ; Koláček, Jan (advisor)
The subject of this master thesis is the elaboration of a study of a curved footbridge leading over the Svratka River. Two variants were created, from which a suspended structure was selected for subsequent modelling and assessment. The footbridge consists of a monolithic bridge deck made of prestressed concrete. The cross section of the bridge deck is designed as an asymmetrical box girder, suspended on one side by a pylon. The pylon is located on the inner side of the bridge deck at the junction of the apex and the centre of the circle and is anchored by hinges to the subgrade.
