Aeroacoustics Simulation and Noise Prediction Services
At 4RealSim, we provide advanced aeroacoustics simulation and CFD consulting using Dassault Systèmes SIMULIA PowerFLOW, a Lattice Boltzmann based solver built for transient, real-world fluid-structure interaction. Our engineers combine deep CFD expertise with aeroacoustics modelling experience to analyse and mitigate noise across complex applications, including rotating machinery, vehicles, consumer products, and industrial equipment.
​
Through validated methods and automation templates, 4RealSim helps engineering teams predict noise sources, correlate results with physical testing, and optimize designs early in development.
Core Aeroacoustics Capabilities
Turbomachinery Aeroacoustics Simulations: Model complex turbulent flows around turbomachinery with true geometry rotation to capture noise generation mechanisms and predict sound radiation from HVAC systems, axial fans, and wind turbines.
Rotor Aeroacoustics Simulations: Accurately predict external flows around rotors in drones and eVTOLs to evaluate aerodynamic performance, identify flow induced noise sources, and support effective noise mitigation strategies.
Vehicle Aeroacoustics Simulations: Analyse external and internal transient flows around vehicles, including moving ground effects and rotating treaded tires, to assess and optimize aerodynamic and aeroacoustic performance.
Automated Workflows for Consistent and Rapid Turn-Around Time: Automation removes manual volume or boundary layer meshing. Standardize aeroacoustics analytics and automated report generation at scale to deliver fast and consistent results.
Automation Templates for Aeroacoustics
To maximize efficiency and tackle highly specialized problems, 4RealSim provides automated workflows for common aeroacoustics analysis. These templates standardize geometry preparation, boundary conditions, model setup, and results extraction while remaining flexible enough to adapt to your specific requirements.
Core Automation Capabilities
Model Efficiency: Reusable model build templates.
