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.

Wing leading edge active flow concept analysis
Mahdal, Vít ; Zikmund, Pavel (referee) ; Popela, Robert (advisor)
This research is focused on substitution of commonly used High-Lift devices by active flow control on the wing leading edge. The analysis is done by CFD tools with use of Reynolds-Averaged Navier-Stokes (RANS) method. In the beginning of the research, commonly used High-Lift devices are described. Solver setting and its explanation together with verification and validation is described in the following chapters. An active flow control concept is testing at the LS(1)-0413 airfoil, for 5 different positions of slots, two different slots widths (h/c= 0,0025 and 0,005) and two different blowing velocities (v_Jv_=2,22 and 4,44). In the end of this paper, physical phenomena of blowing is described together with evaluation of different cases. The best case is compared with Fowler and slotted flap at Reynolds number 2,2 million.
