Aero acoustic simulation for buried gas pipelines.

Advanced aero-acoustic simulations within a soil medium to evaluate sound pressure levels at various sensing points. This involves systematically varying key dimensional parameters to understand their influence on acoustic behavior. The simulations utilize a comprehensive suite of ANSYS modules, including Fluent for fluid flow analysis, Structural for mechanical response, Harmonic Acoustics for acoustic wave propagation, Harmonic Response for frequency-domain analysis, and the Coupled Field Transient module for integrated multi-physics simulations.

The results from these analyses, captured in the time domain, are seamlessly integrated into a Distributed Acoustic Sensing (DAS) system. This integration enhances the system’s capability to detect gas pipeline leakages at an early stage, thereby significantly improving the safety and reliability of pipeline operations. Sponsored by GAIL, this project emphasizes cutting-edge techniques in pipeline monitoring and highlights the critical role of simulation-driven approaches in addressing complex engineering challenges.
