The Study of Implementation of Innovated Products in Production Process
Molík, Tomáš ; Šifalda, Martin (referee) ; Jurová, Marie (advisor)
This student thesis deals with a problem of manufacturing and competition ability of the joint stock company ZVVZ in the range of its manufacturing program - radial fans. The thesis compares the present and the innovated type of small radial fans from the view of manufacturing technology and manufacturing costs. The study comes out the technological documentation and demand forecast of future market. Finally the thesis summaries conditions which are necessary for the successful entrance of the innovated type of radial fans into the manufacturing process.
Calculation of the cooling medium in the asynchronous
Trnka, Zbyněk ; Skalka, Miroslav (referee) ; Janda, Marcel (advisor)
The aim of this master´s thesis was to model the fan for the induction motor, and then to solve this model using Ansys CFX in the terms of flow, when considering the different speeds of rotation of the rotor. The introduction of this work is dedicated to basic terms and definitions from spheres of fluid flow, cooling of the electrical machines, especially to the cooling of the asynchronous machine. There is also attention paid to losses in this machine. Finally, there is modeled radial fan and an air gap of specified induction machine. By using Ansys CFX the flow, which passes from the fan into the air gap, is analyzed.
