Study on Noise Reduction in Turbofan : Effects on Performance and Noise by Improving Outlet Angle of Impeller
スポンサーリンク
概要
- 論文の詳細を見る
A turbofan has been widely used in various industrial fields. In recent years, the need for a turbofan with higher pressure ratio over wider operating flow range under quiet condition is arising. However, the noise usually increases as the increase of the pressure ratio and the widening of the operating flow range. In order to solve these contradictions on the performance characteristics, the impeller with different outlet blade angles were manufactured and tested. When the angle was properly chosen, the aerodynamic performance characteristics developed without the increase of the specific noise level.
