Compressor blade flutter in combined plunge-twist mode shapes
, 2023 Modern aeroengine compressor designs strive to reduce weight and maintain high aerodynamic efficiency. Therefore, the aim of initial compressor designs is to implement novel features that achieve these goals. However, some modern features result in greatly reduced damping, which can lead to vibrational instabilities such as flutter.

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes
Advanced Functional Materials, EarlyView.Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Advanced Functional Materials, EarlyView.Co‐assembly of rationally designed glycosaminoglycan‐binding peptides with sulfated glycosaminoglycans yields supramolecular hydrogels with tunable mechanics and matrix‐mediated cytokine retention. The glycosaminoglycans thereby act as cofactors, driving a coil‐to‐β‐sheet transition that triggers gelation.

Journal of TurbomachineryAbstract The effect of mode shape and reduced frequency on the flutter stability of a linear low-speed compressor cascade was investigated experimentally, employing the aerodynamic influence coefficient (AIC) approach. This paper describes in detail the methodology, experimental setup, and measurement techniques.

One-dimensional morphodynamic model coupling open-channel flow and turbidity current in reservoir
Journal of Hydrology and Hydromechanics, 2017 Traditional depth-averaged morphodynamic models for turbidity currents usually focus on the propagation of currents after plunging. However, owing to the unsteady characteristic of the plunge point locations and the tough conditions of field measurement ...
