Numerical and Experimental Study of Flutter in a Realistic Labyrinth Seal
International Journal of Turbomachinery, Propulsion and PowerLabyrinth seals are commonly used in turbomachinery in order to control leakage flows. Flutter is one of the most dangerous potential issues for them, leading to High Cycle Fatigue (HCF) life considerations or even mechanical failure.

Prediction of transonic flutter for a supercritical wing by modified strip analysis and comparison with experiment [PDF]
Use of a supercritical airfoil can adversely affect wing flutter speeds in the transonic range. As adequate theories for three dimensional unsteady transonic flow are not yet available, the modified strip analysis was used to predict the transonic ...
