Aeroacoustics Simulation of Vacuum Cleaner Motor using PowerFLOW | EuroNorth RUM 2021

RUM2021 ​​​​​​​RUM2021-EuroNorth ​​​​​​​PowerFLOW 
During the 2021 EuroNorth RUM we welcomed Kondwani from Dyson. Kondwani presented "Aeroacoustics Simulation of Vacuum Cleaner Motor using  PowerFLOW" - the abstract is below. 

Dr Kondwani Kanjere is a Lead Noise and Vibration Research Engineer at Dyson Technology Ltd UK. He obtained a Bachelor degree in Aeronautical Engineering and a PhD in Aerodynamics and Aeroacoustics from University of Southampton. He joined Dyson Technology Ltd UK in 2012 and is based at the Research HQ in Malmesbury. His research interests have included airframe noise, jet noise, and turbomachinery noise. He currently supports aeroacoustics research on high speed digital motors using advanced simulation solutions


"At Dyson we continuously strive to find ways to reduce the noise from our products. As part of this effort, an evaluation of the capabilities of PowerFLOW to predict the flow generated noise from a vacuum cleaner motor was performed. The aim was to assess whether PowerFLOW can accurately predict the noise from the motor as measured in the acoustic chamber. Simulations were performed on an isolated motor and the motor integrated into product. The predicted noise level in both cases were in very close agreement with measurements and offered very useful insights into the noise sources and mechanisms."
