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.

Making off-highway equipment, such as construction or agriculture machines, more efficient continues to be a priority after the final phase-in of the U.S. EPA Tier 4 Final emissions regulations. “Some of the companies we work with are running out of credits and unfortunately still struggling with Tier 4,” explained Tristan Donley, Technical Director, Off-Highway Heavy Vehicles North American for Exa, a supplier of software for computational fluid dynamics (CFD).
