Optimization of Fan Aeroacoustics using Design of Experiments

Due to advances in science, technology, materials, and manufacturing methods, devices are becoming lighter, smaller, and packed with new, powerful features. Consumer expectations have also increased to include innovative, high-quality, reliable, and long-lasting devices. This presents a unique challenge for engineers in terms of managing heat generated by devices without compromising customer experiences, and by extension, brand reputation. Engineers must walk a fine line between fan cooling requirements and customer sensitivity to noise.
 
Physical testing of electronic devices in an anechoic chamber is expensive and time consuming, causing product development delays. Often, excessive fan noise is only uncovered in a late prototype testing.
SIMULIA PowerFLOW’s aeroacoustics solution simulates accurate and quick predictions of fan noise levels at different locations, over a wide frequency range. Unlike physical testing, SIMULIA PowerFLOW’s aeroacoustics solution provides both overall noise levels and detailed insights into noise sources and propagation.
 
Webinar Highlights:

• SIMULIA PowerFLOW with DesignGUIDE optimization workflow to optimize the shape of fan blades for noise while maintaining desired airflow performance
• Transient and compressible flow solver based on the Lattice Boltzmann Method (LBM)
• Design of Experiments (DOE) study that visualized noise reduction between the baseline and optimized blades design
