Flow induced noise modelling for industrial piping systems
conference paper
Noise from e.g. gas-transport piping systems becomes more and more a problem for plants located close to urban areas. Too high noise levels are unacceptable and will put limitations on the plant capacity. Flow-induced noise of valves, orifices and headers installed in the installation plays a dominant role. To control such noise problems during the engineering phase, methods must come available, which can predict flow-induced noise, propagation of the noise through the entire system and the effect of the noise to the environment. Noise control measures, such as silencers and pipe insulation, must often be incorporated at this engineering stage. The existing methods and standards for calculating noise generation and propagation, in the frequency range of interest, are incomplete and far from convenient for making calculations on large systems. A better and more efficient description of the flow-induced noise generation and propagation through fluid conveying pipes is required for engineering purposes. This paper presents some advanced methods for modelling of flow-induced noise generation and propagation in piping systems.
