Analysis of the supersonic flow of gas in the differentially pumped chamber EREM
Matloch, Roman ; Vyroubal, Petr (referee) ; Maxa, Jiří (advisor)
This work describes briefly electron microscopy issue and physical model of fluid flow. Then presented diploma thesis will be describing analysis and evaluation of the impact of supersonic flow on the pressure and density in the path of the primary electron beam in the differential pumping chamber. For analysis, evaluation and examination of the issue will be used CAD and CAE (Computer Aided Engineering) programs. At the same time it will be developed a methodology of calculation applicable to supersonic flow in the low pressure system at ANSYS CFX.

Ventilation and air conditioning of the sports hall
Lechnýř, Zdeněk ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The bachelor's thesis deals with the following ventilation equipment of the sports hall. The theoretical part deals with the topic of air distribution in hall buildings. In the practical part of the work, two air handling units are designed. The first air handling unit controls the hot air heating and air conditioning of the gym. The second unit controls the forced ventilation of the facilities for athletes. The project documentation of ventilation and air conditioning for the specified object is elaborated in the final part.

The design of Pelton turbine for given parameters
Pavlíček, Tomáš ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
The aim of this bachelor's thesis is to create a project of a small Pelton’s turbine for laboratory use, focusing on the design of nozzle and blade. Designing these two parts included beam measuring, calculating the losses in the piping and finding the working point of the pump. In its first part this thesis reviews the history, the operating principle and the main parts of the Pelton’s turbine. The next part includes finding the appropriate shape of nozzle and measuring the beam, followed by the calculation of lossy coefficient and efficiency of the nozzle from the measured values. The third part is dedicated to calculation of losses in the piping and finding the working point of the pump. In the last part, blade is designed.

Air-conditioning system of a sports hall
Onderek, Aleš ; Blasinski, Petr (referee) ; Rubinová, Olga (advisor)
The present bachelor thesis consists of three parts: theoretical, computational and design part. The practical part of the bachelor thesis deals with the design of air-conditioning system of a sports hall which includes a gymnasium and its sanitary facilities. The theoretical part is focused on the air-conditioning system of large-volume air spaces and in the end of the theo-retical part, the large-volume air-distiribution system is described.

Air-conditioning of Sports Hall
Švub, Oldřich ; Horák,, Petr (referee) ; Rubinová, Olga (advisor)
The bachelor thesis deals with air-conditioning of sports hall. The aim was to design a two to three air-conditioning devices for the sports hall. Introductory theoretical part is devoted to the history of air conditioning, an explanation of the concept of stratification, the description of terminal elements and description of the selected objects, in which the distribution of air is greater than 4 meters. The theoretical part is followed by part of the calculation and design.

Steam turbine
Vališ, Petr ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
Goal of this dissertation is design of rotary reduction for entered input parameters that it is connected in parallel with reducing station. Further I´m looking into thermodynamic calculation of stage and chosen parts of turbine, making of project design of connection of rotary reduction to steam circulation. Dissertation is concluded by designed cross-section of turbine.

CFD analysis of the airflow for the different types of flowmeters
Drexler, Pavel ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
There are some basic information about pressure sensors and flow in the first part of my diploma thesis. For example turbulent and laminar flow, construction of pressure sensors and basic information abaut Ansys and –Fluent. Main part of this thesis is focused on CFD simulation of pressure and velocity in the vicinity of pressure sensors. I confront this simulated values with measured values in final part of this thesis.
