Analysis of The Effects of Wind on The Steel Ventilated Facade
Kloss, Tomáš ; Žák,, Antonín (referee) ; Hron, Lukáš (advisor)
This master´s thesis analyzes an effect of wind load on the ventilated facade claddings. The analysis is performed on the various types of facades, from unventilated to ventilated facades with a different geometrical arrangement of facade shell. The theoretical part describes the basic knowledge about the theory of flow, turbulence modeling, determining an optimal domain, verification of the calculation model and user interface in the ANSYS software. The final part compares the value of the wind load reduction depending on the change of the gap widths and the size of ventilated spaces. The resulting values are obtained by CFD simulations. The thesis includes a design and an assessment of the steel hall construction.

Application of spectral element method in computations of incompressible turbulent flow
Jiříček, David ; Pech, Jan (advisor) ; Dolejší, Vít (referee)
In the thesis we study incompressible turbulent flow using spectral element method (SEM). We present fundamentals of SEM which can be seen as a combination of spectral method and finite element method. Turbulent flow is described with the help of two-equation k-ω turbulence models. We give reasons for the choice of Kolmogorov's and Wilcox model and implement them in 2D into an existing SEM C++ framework, Nektar++. Analytical solutions of Navier- Stokes equation were found and used as test cases for the implementation of the models. We simulated turbulent flow in channel and compared the results with direct numerical simulation. 1
