| Abstract |
It is important to predict aerodynamic noise early in the design and construction of machines and equipment, in order to reduce the annoyance to people in factories and in the neighbourhood, and in order to improve the quality of products. A theory of sound generation and radiation of cascades, namely blade and vane rows, in flow machines is presented. The sound power of cascades is calculated by use of different models. It is possible to predict the overall noise and the noise spectrum which are related in complicated equations to the geometry, the aerodynamic parameters and operating conditions of the machines and installations. |
