Bingwei Song, Auteur ; Hironori Horiguchi, Auteur ; Yumeto Nishiyama, Auteur |The fundamental characteristics of rotordynamic fluid force moment on the backshroud of a Francis turbine runner in precession motion were studied using model tests and computations based on a bulk flow model. The runner is modeled by a disk pos[...]
