The aerodynamics of centrifugal compressors is a topical issue. as the vibrations and noise reduce the comfort of people who are in proximity to the compressor. The current trend in rotating machinery research is therefore not only concerned with performance parameters but also increasingly with the effect on humans. An analysis of aerodynamic noise based on external acoustic field me... https://unitedssports.shop/product-category/bike-parts-bmx-wheel-rims/
