Aeroacoustic Effects of Fans and Blowers: A Pragmatic Guide for Designers and Engineers

  • A significant percentage of electrical energy consumption is attributable to fans and ventilators of various kinds. They are inextricably linked to our industrial and domestic environment. Low-noise design and development is therefore a key aspect for future systems and machines in urban areas and is a top priority alongside aerodynamic efficiency and mechanical strength. Low noise emissions are required on the one hand to comply with legal guidelines, but on the other hand also to save costs with regard to sound insulation measures on the transmission path (silencers, insulating materials, etc.). This tutorial provides an overview of the sound mechanisms relevant to fans and ventilators and the associated fluid mechanical effects. Practical industrial examples and best practice options as well as their opportunities and obstacles are presented.
