Numerical Analysis Study on Flow Field and Sound Field in Spiral Tube


The model of Realizable κ-ε in fluent of computational fluid dynamics software was used to numerically simulate unsteady turbulent flow in spiral tube. In order to get the sound pressure with time variation diagram and the sound field spectrogram, the situation of flow field was analyzed and the acoustic field was monitored by the FW-H equation. The results… (More)
