Anotace
This project is concerned with computational simulation of air flow in the individual parts of a synchronous machine. FLUENT6 software was used for computational modeling. A model of a machine fan was built, which was used for calculation of ventilation characteristics. Ventilation characteristics were calculated for three ventilator diameters. The aim was to find the operating point for each fan. A model of the asymmetrical inlet to the machine and the distribution of airflow to the stator and rotor was built, which consisted of inlet to machine, axial stator and rotor channels and ten radial channels in the stator packet. A parametric computational model was developed with three main parameters - size of axial stator and rotor channels and size of radial channels. The results of the computer simulation were compared with experimental measurements, which were accomplished on the synchronous generator using a Pitot tube and digital micro manometer.
