Abstract
Description
−ダクトは、ブレードプロフィールの上流で主流から流れを抽出する入口と、渦領域又は減圧領域又はキャビテーション領域に開口する出口と、を備え、
−注入手段は、抽出された流れの通路に配置された弁を備え、この弁は、抽出された流れを主流から通過させる開いた位置と、抽出された流れの通過を妨げる閉じた位置と、の間を動くことができ、
−弁の動きは、適切な制御手段でコントロールされ、
−ブレードプロフィールは、フランシスタービンホイールの複数のブレードのうち少なくとも1つのブレードであり、このブレードは、ランナのクラウンとランナのバンドとの間に配置されており、流れが、ランナのクラウン又はランナのバンドに形成された開口によってランナのクラウン又はランナのバンドから抽出され、この流れが、少なくとも1つのブレードの下流側の端部に流入する。
