Exa's PowerAcoustics application for aeroacoustic simulation can evaluate and improve fan noise with the company's suite of simulation products. Combined with Exa PowerFlow, PowerAcoustics performs accurate aeroacoustic analysis and predicts broadband and tonal noise from rotating machinery, including acoustic peaks related to blade passing frequency. With PowerAcoustics, commercial and off-highway truck engineers can evaluate and hear fan simulation results, using the embedded audio file facility to compare designs and archive outcomes. By performing simulations early in the development cycle, manufacturers have time to optimize fan models, including installation effects, to reduce noise generation, improve passenger comfort, and meet regulation targets.
