| Abstract |
In this paper a method is developed for the calculation of the power of sound generated aerodynamically, especially in the blade and vane rows of axial flow fans. By the use of different acoustic models it is possible to predict the overall noise and the spectrum of sound energy. A comparison is made between the results of computation and measurements of the noise generated by different axial fans and compressors. |
