Electromagnetic field calculation of Induction machine for different mechanical load
Hetflajš, Martin ; Kurfürst, Jiří (referee) ; Skalka, Miroslav (advisor)
This bachelor’s thesis deals with an analysis of the induction machine electromagnetic field distribution with real parameters. Whole analysis was done for three point of the mechanical load by finite element method in ANSYS. In the next part is described a basic theoretically research of the electromagnetic field and also preliminary survey of the numeric method for FEM. This thesis also contains an analysis of electromagnetic model of analyzed induction machine with detailed description of each analysis step and in conclusion the results summary was done.
Calculation of transformer cooling
Hetflajš, Martin ; Cipín, Radoslav (referee) ; Janda, Marcel (advisor)
This master´s thesis deals with influence of forced air flow from the ventilators on the power transformer cooling. For this analysis was used simulation software ANSYS CFX, that uses the finite volume method for calculations of dynamic properties of liquids. In the introduction of the thesis is presented the basic terminology of fluid flow, temperature fields and theory of transformers. The simulation is divided to the analysis of flow through the left and right radiator models.
