Aero-Acoustic Modeling
After significantly reducing primary noise sources, such as road or automotive engine noise or structural hydraulic noise, engineers today are faced with the complex task of reducing all types of flow-induced noise found in various markets.
Aero-Acoustic Modeling coupled with the BEM (Boundary Element Method) technology helps engineers to accurately predict and solve aero-acoustic noise problems, ranging from fan noise in electrical appliances and wind turbines to turbulence-based noise in aircrafts.
Aero-Acoustic Modeling uses a pragmatic approach to predict aero-acoustic noise, based on aero-acoustic analogies. It derives equivalent aero-acoustic sources from flow equations calculated with any Computational Fluid Dynamics (CFD) vendor, supporting the CFD General Notation System (CGNS) interface. It then calculates the resulting radiated or scattered noise using BEM technology.
This efficient and cost-effective solution only requires system boundary modeling, resulting in relatively small acoustic models that are easy to create and check, yet provide accurate solutions to real-life problems. Powerful post-processing tools enable engineers to analyze and visualize results for acoustic refinement.
