Evaluation of the possibility of modeling the vibration-noise characteristics of the pipeline and their elements by the method of computer simulation
The article discusses the main provisions and problems in predicting the vibration and noise characteristics of various elements of pipeline systems. One of the possible ways for the sequential solution of problems of calculating the parameters of hydrodynamic and acoustic noise both in the pipeline itself and in the surrounding area is proposed. To study the vibration and noise characteristics of pipeline systems, it is recommended to use a combination of Fluent, Modal (Modal Acoustics) and Harmonic Responce (Harmonic Acoustics) modules based on the Ansys Workbench platform. The results of computer simulation for pipeline elements, such as a pipe with a flange, an elbow, a pipeline of variable cross-section, etc. are presented. It is noted that the simulation results have a high convergence with field tests.
