Fan Noise Reduction using Acoustic Metamaterials towards Efficient Data Centers
Wasala, Sahan (2022)Unwanted sound from cooling fans has been a significant obstacle that limits the performance of data center Hard Disk Drive (HDD) storage systems. Acoustic metamaterials (AM) can be a solution to this problem. AM’s can ... -
Numerical analysis of acoustic noise from an electronic cooling fan at flow disturbed by an external obstacle
Wasala, Sahan; Persoons, Tim; Sosseh, Raye; Stevens, Lon (internoise2022.org, 2022-08-24)Axial cooling fans are widely used in data center dense Hard Disk Drive (HDD) storage systems. However, these fans emit high noise levels and degrade HDD performance at certain frequencies. Flow at the fan's inlet can ... -
Reduced-order aeroacoustic modeling of electronics cooling fans
Zhao, Wenguang; Wasala, Sahan; Persoons, Tim (Society of Acoustics, Singapore, 2022)As the trend of compact packaging and high-density thermal management continues, the acoustic noise emission from electronics cooling fans is becoming a critical concern. High-fidelity computational fluid dynamics (CFD) ... -
Towards Quieter Air-Cooling Systems: Rotor Self-Noise Prediction for Axial Cooling Fans
Persoons, Tim; Zhao, Wenguang; Wasala, Sahan (2022)Aeroacoustic noise is seen as a major threat to the survival of air cooling for electronics systems. The application of numerical noise prediction methods is highly constrained by computational costs. A reduced-order model ...
