摘要:

直接空冷系统的噪声主要包括风机群的气动噪声,其中偶极子声源占主导地位。利用Fluent声学模块对空冷岛进行了流场模拟和噪声估算,可以看出Fluent可对流场进行有效模拟,可考虑采取降低低频噪声的方式来改善直冷系统对周围环境的影响。

Abstract:

Noise of direct air cooling system mainly consists of fan group aerodynamic noise and is mainly from dipole. Air cooling island fluid field simulation and noise estimation was carried out based on Fluent acoustics module. Which indicated that Fluent effectively simulated fluid field. To improve environmental influence from direct air cooling system, lowering low frequency noise could be considered.
