Unlock the future of vehicle quietness! Discover groundbreaking advancements in reducing vehicle interior noise with our conference paper, “Aeroacoustics Simulations of Full-Scale Sedan Vehicle Towards Interior Noise Predictions” (ref AIAA-3825). This in-depth study, a collaboration with Honda, leverages large eddy simulations (LES) to accurately predict and analyze the sources of wind noise affecting modern sedans.
As vehicles electrify, wind noise is replacing traditional engine noise as a primary concern. Our research shows how CFD can advance early-stage design for quieter cabins.
Highlights:
- Advanced Simulations: Learn how our low-Mach (Helmholtz) flow solver Fidelity LES Solver, formerly Cascade CharLES, accurately captures hydrodynamic and acoustic pressure fluctuations.
- Real-World Validation: See how our simulations align with Honda’s wind tunnel measurements, pinpointing noise sources like side windows and A-pillars.
- Efficiency Gains: Explore the impressive computational throughput achieved with GPU acceleration, cutting simulation times significantly.
