The aim of the project was to get familiar with the environment of ANSYS CFX, create several models of fans and synchronous machine model in Autodesk inventor, create model of cooling medium flow through the machine with these fans and evaluation of results. Firstly the thesis describes the synchronous machine itself, losses of the machine, the flow of power of synchronous machine and methods of its cooling. Next the thesis describes each kind of heat transfer, laminar and turbulent flow. The thesis also refers of kind of the fans and the program used to calculate the flow Ansys CFX, including the method that Ansys used to calculate. The work describes the individual modification of fans and setting of calculation in ANSYS. Then displays the results of the analysis these fans for different numbers of fan blades and for modification of the fan. Then the thesis analyzes selected modifications due to changing speed. In the last chapter shows the analysis of flow in the machine with three different fans. In particular, there is shown the mass flow rate, pressure and its distribution on areas for evaluation.
