Návrh sacího traktu pro vůz Formule SAE / Engine Intake Manifold for Formule SAE

Řehák, Ivo January 2008 (has links)
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.

Návrh a optimalizace sacího a výfukového potrubí zážehového motoru / Intanke and exhaust manifold for racing engine

Chuchma, Ondřej January 2010 (has links)
This Master’s thesis is focused on design and optimalization of intake and exhaust system of the C20XE engine. It is four-cylinder gasoline engine with stroke volume of two litres, which was produced by car company Opel. This engine is determined for Opel Astra F automobile, that is build for racing. For optimalization of dimension parameters there is used a Lotus Engine simulation software, which simulates one-dimension gas flowing in manifold. 3D CAD models are made in Pro ENGINNER software.

Stanovení druhé viskozity kapaliny z měřených tlakových pulsací. / Assessment of the second viscosity coefficient from measured pressure pulsations.

Černý, Ondřej January 2010 (has links)
Diploma thesis deals with problem of assessment of the second viscosity and acoustic velocity coefficients by the different liquid´s flow in pipe from measured pressure pulstation created by diaphragm pulsator. For the solution is used a transfer matrix model and for the data evaluation a genetic algorithm in „Facharp.exe“ program. Modal analysis in problematic part of the measured stand is realized to find a wave shapes and natural frequency of a pipe. The results are for the reason of clearness processed into „MS Excel“ program and fetched to the charts which shows depedence of a second viscosity and acoustic velocity coefficients on a various flow as the final result.

Rotující odtržení v prostoru odstředivého kompresoru. / Rotating stall in a centrifugal compressor.

Guzej, Michal January 2012 (has links)
This thesis deals with a procedure for determining the complete processing of aerodynamic flow instabilities (rotating stall and surge) in a centrifugal compressor. At small flows the performance of a compressor system is limited by the surge line, which is caused by flow instabilities. Numerical solution is obtained using the method of transfer matrix. This system is simulated through several models with local resistances that represent the dissipation of pressure energy. Pulses are excitated in these models by the pressure jump placed before the centrifugal compressor. From the frequency-amplitude characteristics for the selected range of frequencies and flow the impedance characteristic of the compressor system is determined. We are looking for problematic frequencies in this characteristic that cause flow instabilities in the compressor system.

Dynamické radiální síly působící na oběžné kolo odstředivého čerpadla / Dynamic radial force on centrifugal pump impeller

Nováková, Naděžda January 2012 (has links)
This thesis deals with the radial forces acting on the impeller of a centrifugal pump. It focuses on the centrifugal pump type BETA 26. It addresses forces acting on the pump shaft. These forces are converted into the impeller. The most extensive part of this thesis is devoted to the experimental measurement and evaluation. The results are summarized and processed graphically.

Využití vzduchových pružin u závodního vozu / The use of air springs for race car

Blažek, Jakub January 2013 (has links)
This diploma thesis studies the use of air springs for race car, precisely Formula Student race car. Research part of the thesis deals with choosing suitable air spring for given application. In practical part, there is computation of parameters for appropriate setting of air spring, so it will comply with the rules of Formula Student. There is also simulation of air spring functionality in real use.

Vytvoření cenových podkladů pro stanovení tržního nájemného v bytech pro lokalitu Brno - Královo Pole / Creation of Pricing Details for the Determination of Open-market Rent for Apartments for the Brno-Královo Pole Locality

Vrbková, Lucie January 2011 (has links)
The goal of this diploma thesis was creation of pricing details for the determination of open-market rent without regulation of prices for apartments for the Brno – Královo Pole locality. As a basis for diploma were used data of achieving market rents taken from databases of two estate agencies. Apartments were divided into categories according disposition on small, middle, large and luxury. In each category was defined a standard from which was basic price made. After that were created twelve groups which enabled to judge influence of each factor on rent. As a factor (quantity) influencing a rent were defined – state of property, characteristic type of construction, equipment of apartment. As a result was total summary of basic rental prices for each categories relating to floor area and was defined influence of each factor.

Podnikatelský plan pro založení krejčovského salonu / Business Plan for the Foundation of the Tailoring Salon

Pospíšilová, Marie January 2016 (has links)
The thesis focusses on presenting a real business plan in the field of dressmaking services in Letovice. The theoretical part of this thesis presents the basic theoretical knowledge of dressmaking itself. The practical part of the thesis focusses on market research. According to an analysis of the marketplace and competition in this area, a business plan proposal has been created. This proposal shows the likely success rate of realization.

Membránová stěna kotle s pokročilým řízením průtoku / The membrane wall of the boiler with an advanced flow control

Češla, Martin January 2016 (has links)
The master thesis deals with hydraulic characteristics of once-through boilers and describes the problems which may arise during the flow of water through the evaporator. Especially the formation of aperiodic instability of the evaporator and hydraulic uniformity amongst every steam generating tube. The thesis describes parameters, which cause these problems, and solutions how to deal with them. The calculation has been done for evaporator of the boiler called K2 located in power station in Chvaletice.
