Aeroacoustics Simulation and Noise Prediction Services
At 12Simulate, we deliver advanced aeroacoustics simulation and CFD consulting using Dassault Systèmes SIMULIA PowerFLOW, a Lattice Boltzmann based solver developed for transient, real-world fluid structure interaction. Our engineers combine extensive CFD expertise with aeroacoustic modelling experience to evaluate and reduce noise in complex applications, including rotating machinery, vehicles, consumer products, and industrial equipment.
Through validated methodologies and automated workflows, 12Simulate supports engineering teams in identifying noise sources, correlating simulation results with physical testing, and optimizing designs early in the development process.
Core Aeroacoustics Capabilities
Turbomachinery Aeroacoustics Simulations: Simulate complex turbulent flows around turbomachinery with true geometric rotation to capture noise generation mechanisms and predict sound radiation from HVAC systems, axial fans, and wind turbines.
Rotor Aeroacoustics Simulations: Accurately simulate external flows around rotors in drones and eVTOL systems to evaluate aerodynamic performance, identify flow-induced noise sources, and support effective noise reduction strategies.
Vehicle Aeroacoustics Simulations: Analyze transient external and internal flows around vehicles, including moving ground effects and rotating treaded tires, to evaluate and optimize aerodynamic and aeroacoustic performance.
Automated Workflows for Consistent and Rapid Turn-Around Time: Automation eliminates manual volume or boundary layer meshing while standardizing aeroacoustic analysis and automated report generation at scale to deliver fast and consistent results.
Automation Templates for Aeroacoustics
To maximize efficiency and address highly specialized challenges, 12Simulate provides automated workflows for common aeroacoustic analyses. These templates standardize geometry preparation, boundary conditions, model setup, and results extraction while remaining flexible enough to adapt to specific project requirements.
