Sekundarni naslov: | Prediction of flow generated noise and optimization possibilities |
Sekundarni povzetek: | Within presented thesis validation of numerical simulation regarding dynamic phenomenon of flow generated sound was performed. An appropriate theoretical basis was given, followed by the integral processing of an element with a typical phenomenon of whistle in the form of an experiment carried out in the Laboratory for pumps, compressors and technical acoustics at the Faculty of mechanical engineering in Ljubljana. The main part of the master's thesis covers the settings and start of numerical simulation in the Fluent programming environment. The analysis of influential variables is followed by the fast Fourier transformation of the sound field and the image processing of the animation of the flow field with our own program code is done. The latter showed the interdependence of the characteristic amplitudes in the frequency domain of the flow field and the acoustic phenomenon. |
