概要
- 論文の詳細を見る
Unsteady aerodynamic responses of a mistuned cascade subjected to incoming wakes from an upstream cascade are investigated in this study, where the extended Nishiyama-Funazaki method is employed. Numerical calculations are made, focussing on the effects of stagger angle mistuning of the cascade. It is accordingly found that there is some possibility of reducing wake-induced unsteady forces by controlling stagger angles without the severe expense of cascade performance deterioration. In addition, intense correlation between unsteady lifts and the corresponding steady lifts in the case of in-phase incoming wake conditions is observed.
