3D simulation of an advanced futuristic aircraft showing airflow and turbulence analysis using CFD for aeroacoustic performance.

Noise control is a growing priority across industries ,  from aerospace and automotive to consumer electronics and renewable energy. SIMULIA PowerFLOW offers advanced aeroacoustic simulation capabilities, allowing engineers to predict and reduce flow-induced noise early in the design process. This leads to quieter, more efficient products, shorter development cycles, and fewer costly design iterations. 



Why SIMULIA PowerFLOW? 

Built on the lattice-Boltzmann method (LBM) and Very Large Eddy Simulation (VLES) turbulence modeling, PowerFLOW provides high-fidelity CFD and acoustic analysis in one integrated platform. It accurately simulates unsteady airflow, captures interactions between flow and structure, and reveals how noise is generated and transmitted. Engineers can address issues like tonal noise, turbulent wakes, and surface pressure fluctuations ,  all before a prototype is built. 

PowerFLOW excels in: 


  • Accurate noise prediction: Its LBM-based solver captures complex, unsteady flow structures critical for realistic aeroacoustic performance. 

  • Comprehensive turbulence modeling: VLES handles a wide spectrum of flow regimes, from subsonic HVAC systems to transonic aircraft components. 

  • Effortless mesh generation: High-quality, automated volume meshes save time and remove manual bottlenecks. 

  • Rotating component simulation: Realistic modeling of fans, propellers, and compressors ensures precision in both noise and aerodynamic results. 

 

To support interpretation and decision-making, PowerFLOW includes tools like PowerACOUSTICS (for sound propagation and source localization) and PowerVIZ (for pressure, flow, and turbulence visualization). Automated workflow templates also help engineers iterate faster and explore more design alternatives. 



Industry Applications 

PowerFLOW is trusted across engineering sectors where acoustic performance matters: 

  • Automotive – cabin noise reduction, HVAC optimization, underbody and mirror airflow 

  • Aerospace & defense – airframe and landing gear noise, ventilation analysis, passenger comfort 

  • Energy – wind turbine blade noise prediction and control 

  • Consumer electronics – quieter fans, better thermal/acoustic trade-offs in compact devices
