摘要：
The mechanism of noise decreasing of a centrifugal blower by tooth shape vane was studied in this text. The experiments showed that the effect of tooth shape vane on noise decreasing was related to the vortex state of airflow in vane passage. For Reynolds number Re=4×105 [similar to] 6×105, a better effect of noise decreasing was obtained corresponding to the noise decreasing 4 [similar to] 5 dB. Beyond the above values of Reynolds number, the tooth shape Vane didn't act on noise decreasing at all. At tooth distance t=b/5 and tooth altitude h=b/10 the level of noise reached 2.5 dB decreased by 2.3%. However, its average kept constant and the average efficiency decreased by only 1.5%.
