Kirchhoff-BEM 을 이용한 Plenum Fan 소음해석
Acoustic Analysis of Plenum Fan using Kirchhoff-BEM
- 발행 : 2004.12.01
초록
To numerically construct the sound fields by a plenum fan mostly found in Air-Handling Unit (AHU), the Kirchhoff-BEM approach was applied to the near-field data of a turbo fan. The scattering effects were found to be significant by the plenum box structure for high-frequency components of source. The directivity petterns and sound pressure levels were also dependent upon the helmholts number which must be considered of the design stage for sound reduction program.
