Experimental Study of Axial Clearance Influences on the Noise Characteristics of Contra-rotating Fan |
| |
| Abstract: | Based on the test study of the noise characteristics of some type of counter-rotating axial fan,the noise spectra curves and the variation curve of A-weighted sound level corresponding to various axial clearances are acquired.The variable regulations that the revolution and eddy noise change as the axial clearance varies are analyzed in detail.It provides a useful reference to decrease contra-rotating axial fan's noise. |
