Abstract Blade flutter is a complex phenomenon that can lead to serious damage or failure of turbomachinery
systems. Predicting and mitigating blade flutter is therefore an important aspect of the design and analysis
of these systems[1]. In this paper, we present a comparative study of two representative methods for blade
flutter predictions: the energy method and the computational fluid dynamics/computational structural
dynamics (CFD/CSD) coupled time-domain method. The energy method is a decoupled approach that uses
a simplified model of the blade and fluid-structure interaction to calculate the stability boundaries of the
system[2]. The time-domain method, on… More >
