Rationalisation of manipulation shop
Vičar, Miroslav ; Neužil, Karel (referee) ; Hlavenka, Bohumil (advisor)
The aim of this thesis is to reach a distinctive rationalization of the production and assembling plant of Cargo Van Brno company. In the project of new lay-out of the production area were all restrictions given by management of the company and by owner of the property strictly met. Technological changes of the process plan and investments suggestions are determined by the company's strategic plan.

OPTIMIZATION OF WELLNESS AIR CONDITION
Kysilka, Michal ; Zubíček, Vojtěch (referee) ; Šikula, Ondřej (advisor)
The theme of diploma thesis is a design optimization of air distribution in swimming-pool hall with regard to free water surface evaporation. This problem was solved according to determined criterions with the aid of CFD simulation. Experimental measurement part of the thesis deals with evaporation problems where own formula for this physical phenomenon is determined. This formula is compared with already known algorithms. Author suggests that such formula might be integrated in CFD software.

Ventilation calculations in synchronous machine
Judas, Jan ; Deeb, Ramia (referee) ; Janda, Marcel (advisor)
The aim of the project was to get familiar with the environment of ANSYS CFX, create several models of fans and synchronous machine model in Autodesk inventor, create model of cooling medium flow through the machine with these fans and evaluation of results. Firstly the thesis describes the synchronous machine itself, losses of the machine, the flow of power of synchronous machine and methods of its cooling. Next the thesis describes each kind of heat transfer, laminar and turbulent flow. The thesis also refers of kind of the fans and the program used to calculate the flow Ansys CFX, including the method that Ansys used to calculate. The work describes the individual modification of fans and setting of calculation in ANSYS. Then displays the results of the analysis these fans for different numbers of fan blades and for modification of the fan. Then the thesis analyzes selected modifications due to changing speed. In the last chapter shows the analysis of flow in the machine with three different fans. In particular, there is shown the mass flow rate, pressure and its distribution on areas for evaluation.

Heat exchangers for air-conditioning
Pavlíček, Michal ; Jaroš, Michal (referee) ; Hejčík, Jiří (advisor)
The thesis is divided into 2 parts. The first part deals with classification and characterization of heat exchangers. The sizing process of plate heat exchangers is described and demonstrated in the second part. Obtained results are compared with real plate heat exchanger produced by Güntner Company.

Intake Manifold for Single-cylinder Engine
Pavličík, Lukáš ; Janoušek, Michal (referee) ; Svída, David (advisor)
The aim of this diploma thesis is to create a thermodynamic computational model of a single cylinder IC engine for the Formula SAE car. The single cylinder SI engine KTM 500 EXC is considered as a powertrain unit. The intake manifold of the serial enduro motorcycle is modified according to the Formula SAE 2014 rules. Analysis of the one dimensional flow is performed by using Lotus engine simulation software.

Engine Intake Manifold for Formule SAE
Řehák, Ivo ; Blaťák, Ondřej (referee) ; Svída, David (advisor)
Thesis is bend on design of intake manifold for car Formula SAE. For driving of this car is used engine Yamaha YZF R6 (2005). Design of intake tract is processed so that agrees with rules and specifications for cars Formula SAE. For restriction of engine performance is in intake tract installed restrictor. For filling efficiency uplift of engine is used the resonance effect in intake pipes. Analysis of flow is carry out on simulation software for analyses of one dimensional flow.

Computational tool for fluid flow of gases through nozzles
Kozáková, Kamila ; Zálešák, Martin (referee) ; Klimeš, Lubomír (advisor)
This bachelor's thesis deals with thermodynamic relations of one-dimensional, adiabatic and steady flow through the duct. Thermodynamic terms, equations and principles, required for understanding the problems of fluid flow, are summed at the beginning. The greatest attention is paid to step-by-step solution of each case, which can occur. These analyses were implemented in a software for solving thermodynamic problems. Scripts and the graphical user interface were created in a programming language Python using its libraries. Last part of this work is focused on evaluating and testing problems of fluid flow through the ducts.

Bladeless fan cooling module
Šišpera, Adam ; Vacula, Jiří (referee) ; Bazala, Jiří (advisor)
Tato diplomová práce se zaměřuje na prozkoumání možností implementace bezlopatkového modulu ventilátoru založeného na Coanda efektu v chladícím systému osobního vozidla. Jejím cílem je prozkoumat proveditelnost takového řešení, jeho provozní charakteristiky a stanovit soubor doporučení pro návrh konkrétního designu. Vhodný chladící modul je navržen, následně hlouběji testován a jeho funkčnost je ověřena také reálným experimentem.
