하우징이 환기장치 홴의 성능에 미치는 영향에 대한 연구

The purpose of this study is to investigate the effects of the housing shape and clearance between the blade tip and housing of a fan. Siroco fan and turbo fan, which are widely used for the ventilation system, are selected in this study, and square housing and circle housing are designed for each fan. Static pressure, power consumption, efficiency and noise are tested and analyzed. In case of siroco fan, much better performance are found in the smaller clearance and circle housing rather than squre housing. On the other hand, the housing shape and clearance weakly affect fan performance for the turbo fan.
