Numerical Simulation of Noise Generated by Shear Layer Instabilities
Šálený, Vratislav ; Kozubková, Milada (referee) ; Paur, František (referee) ; Tippner,, Jan (referee) ; Katolický, Jaroslav (advisor)
Predicting and inhibiting aerodynamically generated noise for fast moving vehicles such as cars, aircraft and trains is increasingly important. The tonal noise generated by the shear-layer instability of air flowing around the cavity opening is especially one of the most significant and most intense sources of aerodynamically generated noise. Computational aeroacoustics (CAA) based on the CFD simulations of compressible Navier-Stokes equations offers the most general approach to predicting those aerodynamically induced sounds. Aeroacoustics is practically always associated with turbulent flow and turbulence is the major challenge for CFD simulations. Four different turbulence modelling approaches are examined in this work. Three of them belong to the LES method category and one uses the URANS approach. Appropriate numerical discretization and iteration schemes have been identified for each of these approaches and implemented in the OpenFOAM open source CFD platform. The accuracy, computational performance and convergence reliability of those schemes have been subsequently studied during three-dimensional CFD simulations on a model of a suitable real object. The CFD simulation results are validated by a measurement. An organ pipe has been chosen as the object of this CAA research because it uses self-sustained oscillations, commonly referred as shear-layer (Rossiter) modes, as the source of its tone generation. The numerical simulation of the shear layer modes, respectively the noise generated by instability in the shear layer, is the subject of this work.

Forest figuration
Jasparová, Lucie ; Bulava, Petr (referee) ; Ambrůz, Jan (advisor)
The bachelor's thesis Forest Figuration is set in the forest around Horní Loučky. In trees, trunks, uprooted roots and landscapes, I look for elements reminiscent of the human body. This process is recorded by various techniques. The whole work is accompanied by social separation, exacerbated by the pandemic of the Covid-19 disease, is based on closing in nature, watching natural cycles and respecting the landscape itself. The work is a collection of works within an exceptionally long time in the forest and is also an initiating moment for further development in later work.

Residential Complex in Brno - Komín
Adamus, Jan ; Vítek, Jiří (referee) ; Kristek, Jan (advisor)
LES IS MORE - to paraphrase the original quote by Robert Browning, but the better known by Ludwig Mies van der Rohe. Or FOREST IS MORE. Trying to merge with associated forest experiment with free urban structure. The layout generous organic architecture. Communication and interstices in an apartment building as a social space.

Valuation of a Forest
Rumanová, Jana ; Scheuer, Pavel (referee) ; Alexandr, Pavel (advisor)
The aim of the thesis was to explore current approaches used for valuation according to the valuation regulation. The next aim was to choose appropriate method for finding usual price and compare it with the price assessed determined by administrative methods according to Valuation Decree. Comperative method was the chosen method. There are six forest properties from The Czech Republic evaluated in the practical part of the study. The conclusion of the thesis summarizes detected information from the area of valuation of forest.

Spiritual brownfield Olomouc - Zlín
Scholzová, Simona ; Nový, Jindřich (referee) ; Štěpán, Marek (advisor)
The topic of the thesis is the proposal of a pilgrimage site in the area of the source of the spring Svatá Voda near Malenovice - Zlín. The building is located on the nearest top site near the existing spring and it dominates its surroundings. The design is based on a circle symbolizing eternity, harmony - Christianity surrounding the Paradise yard. This ring is intersected by four shards that represent disruption of harmony - humanity. These two types of masses are contrasting, distinguished by both shape and material. There is a church in the largest shard, in the smaller shards there are other smaller chapel or individual prayer rooms. In the ring, which is broken into fragments, there are located rooms like a reception, area of the church with, restaurant and technical facilities, non-profit offices that manage the area, together with a therapist's office. There are rooms with accommodation, classrooms and workshops for retreats as well.

ON THE PASNIK
Siegelová, Kateřina ; Vlková, Veronika (referee) ; Klímová, Barbora (advisor)
The topic of my thesis On the Pasník a time and decomposition. I have produced small houses from natural materials and placed them in a forest. The subject of my work is to record the flow of time. The outcome of my work is time based large-formal drawing. The buildings on the drawing gradually collapse and disappear. Thus I have created the time drawing.

New town hall for the district Brno-North
Cejpek, Petr ; Němec, Josef (referee) ; Ruller, Ivan (advisor)
The aim of this diploma thesis is to propose the Town Hall for the city part Brno-sever (Brno-Nord). The Town Hall is placed in a newly designed urban structure, which is located on the territory of today's barracks in Černé Pole. The locality is located in the imaginary geometric center of the city and because of it the site is becoming a convenient location for the Town Hall. The main aim was to create the Town Hall changing during the time, which would respond to the additional larger footprints to the place and would respond to the adding further spaces not only with the function using for the purposes of the Hall. The new Town Hall is designed to enrich the urban space.

Residential Complex in Brno - Komín
Kudelová, Barbora ; Kunat, Bohuslav (referee) ; Marek, Jiří (advisor)
The area is located in Brno, close to the Svratka river. It has got a very good residental background, to its inhabitants it offers many possibilities of living. Also by traffic, it is very easily connected with the center, either by car or by a public transport. Komin is a very atractive place for living and even with nowdays modern age it still carries its old village atmosphere and gives the tranquility and nature to whom live there. And especially the forest was one of the conceptual ideas for me.

WATER + TOWN * SPORT AND RELAX CENTER
Pavolová, Soňa ; Ing.arch. Jan Májek. Ph.D. (referee) ; Poslušná, Iva (advisor)
With project I present a make more attractive part of the territory of the dam, through which I bring two new paths for visitors from the coast and the other from the surface. The overall objective of the procejt is to attract visitors to the dam for more than one day trip or just a walk. The number of hotels and guesthouses on the dam is excessive. I have therefore decided to offer nature lovers accommodation in the country in the immediate vicinity of water while ensuring the necessary comfort. The objective of the present proposal is to present a potential year-round use options of Brno dam - Spa in the frozen surface of the dam, accommodation for schools, and summer camps could revitalize this part even during other year periods.
