Numerical simulation of incompressible fluid flow by the spectral element method
Pokorný, Jan ; Hlavička, Rudolf (referee) ; Čermák, Libor (advisor)
Tato diplomová práce prezentuje metodu spektrálních prvků. Tato metoda je použita k řešení stacionárního 2-D laminárního proudění Newtonovské nestlačitelné tekutiny. Proudění je popsáno stacionarní Navier-Stokesovou rovnicí. Dohromady s okrajovou pod- mínkou tvoří Navier-Stokesův problém. Na slabou formulaci této úlohy je aplikována metoda spektrálních prvků. Touto discretizací se získá soustava nelineárních rovnic. K obrdžení lineární soustavy je použita Newtonova iterační metoda. Podorobný algorit- mus tvoří jádro Navier-Stokeseva solveru, který je naprogramován v Matlabu. Na závěr jsou pomocí tohoto solveru řešeny dva příklady: proudění v kavitě a obtékání válce. Přík- lady jsou řešeny pro různé Reynoldsovy čísla. První od 1 do 1000 a druhý od 1 do 100.
The Marketing Mix Proposal
Miholová, Pavla ; Pokorný, Jan (referee) ; Novák, Petr (advisor)
The thesis focuses on the definition of the marketing mix in the selected companies. Describes how should look the marketing mix and a satisfied customer. The work contains proposals to improving customer satisfaction, which could contribute to the development and success of the company.
Database of typical clothing for cabin of cars
Toma, Róbert ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
In this bachelor thesis, there are processed databases of typical clothing for cabin of cars. Data are based on information from survey for both women and men for three seasons – summer, transitional season and winter. There are mentioned factors which affect thermal comfort and thermoregulation of human body. The thesis includes options how to measure thermal comfort and how we can evaluate results on different scales. Next, I process the way how we measure thermal resistance of each databases of clothing. Measurements are placed in climate chamber in VUT Brno and we are using manikin Newton made by Measurement technology Northwest. In the end, we mention some results and comparison of both genders.
Real consumption of primary energy of plug-in hybrid and electric cars
Bochníček, Ondřej ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
The topic of bachelor thesis is to evaluate a consumption of primary energy in electric cars and plug-in hybrids depending on the place of the operation and also to compare a particular representative with similar classic cars with combustion engine. Another criterion used for evaluation is the emission of carbon dioxide for one driven kilometer. For the consumption of primary energy in electric cars and plug-in hybrids is essential to know how is the electricity produced in the chosen area. With the energy mix of each state, characteristics of given ways of producing electricity and consumptions of selected cars the consumption of primary energy of selected cars and emission of carbon dioxide for one driven kilometer were determined. From the computed data results, that the lowest energy consumption have the electric cars driven in countries with dominant representation of renewable energy sources. Conversely the worst conditions are in the countries with high part of fossil fuels in electricity production. From the comparison of single electric cars and plug-in hybrids with classic cars results that electric cars or plug-in hybrids are at the time of writing this thesis practically in all cases more energy efficient and also produce less emission of carbon dioxide.
Assessment of thermal comfort in buildings
Procházka, Aleš ; Pokorný, Jan (referee) ; Charvát, Pavel (advisor)
This bachelor thesis summarises knowleges about methods used for assessments of thermal comfort in buldings. In opening part of thesis is thermal comfort introduces as important part of overall satisfaction with indoor environment. There are also described fyziological basics and ways of thermoregulation and individual elements of thermal balance. Next part of thesis is focused on thermal and humidity factors of indoor environment. Some combinations of these factors form thermal comfort. Main part of thesis describes methods of assesments of thermal comfort using PMV and PPD indices. For practical uses there are examples of comfort diagrams, which are based on PMV index, Thermal Comfort Meter and Thermal Manikin. Last part contains description of some instruments for measurement of used physical values.
Inclined belt conveyor for foundry sand
Vaňous, Ondřej ; Pokorný, Jan (referee) ; Malášek, Jiří (advisor)
The purpose of the bachelor thesis is the construction design of the belt conveyor for the transport of foundry sand with the transport capacity of 70 tons per hour. The bachelor thesis includes the functional calculation performed according to the norm ČSN ISO 5048. Moreover, the bachelor thesis designs the drive of the conveyor and the strength calculation of the drive shaft and the idler drums.
Research of silage and self loading trailers and autostack automatic bale loaders
Wojnar, Pavel ; Pokorný, Přemysl (referee) ; Pokorný, Jan (advisor)
The aim of the bachelor thesis was to make a study of agricultural trailers from different agricultural machinery producers focusing on self-loading wagons, silage trailers and pressed straw self-loading conveyers. The first part of the thesis gave a short description of agricultural machinery producers and their products. In the second part of the thesis there were described compared parameters with the calculation of own parameters. These parameters were drawn into graph to make the bachelor thesis clear and individual products were according to mentioned parameters compared. The last part focused on the comparison of agricultural machinery producers with respect to non-numerical criteria such as the position of the producer on the market, guarantee and customer service etc.
Study of agricultural tractors with weight over 9 tons
Slimařík, Dušan ; Kašpárek, Jaroslav (referee) ; Pokorný, Jan (advisor)
This bachelor’s thesis treat about study of agricultural tracotors with weight over 9 tons. First part relates with products offered for Czech market. Next part compares products by main and variable technical parameters. Last part of this thesis shows preferences of each manufacture and give short description of chosen products and their details, consequently the best product is determined.
Research of 3 axles articulated haulers
Guzej, Michal ; Kašpárek, Jaroslav (referee) ; Pokorný, Jan (advisor)
The object of this work is the study of product from manufacturers 3 axle articulated dump truck. One task is to compare the product with fundamental and technical parameters relative. The aim is to show some major and secondary producers and also to determine which of the products has the most priority and which manufacturers offer the best products on the market.
Using of a vehicle simulation on a surface in current vehicle development and motorsport
Keprt, Michal ; Pokorný, Přemysl (referee) ; Pokorný, Jan (advisor)
With increasing competitive is higher pressure for car producers. It is the reason why car producers are forced make development of cars more efficient and faster. They use simulation and modeling that is why there are present some most widely used types of simulations. I introduce some kinds of programmers which can make these simulations. There are present also several examples how to improve these results of simulations and modeling.
