Numerical Investigation of a Dynamic Stall on a Single Rotating Blade
Aerospace, 2021 Dynamic stall is a phenomenon on the retreating blade of a helicopter which can lead to excessive control loads. In order to understand dynamic stall and fill the gap between the investigations on pitching wings and full helicopter rotor blades, a ...

The Dynamics of SecM-Induced Translational Stalling
Cell Reports, 2014 SecM is an E. coli secretion monitor capable of stalling translation on the prokaryotic ribosome without cofactors. Biochemical and structural studies have demonstrated that the SecM nascent chain interacts with the 50S subunit exit tunnel to inhibit peptide bond formation.

Dynamic Stall Characteristics of Thick Wind Turbine Airfoils
Wind EnergyThis paper studies the dynamic stall characteristics of thick flatback and nonflatback wind turbine airfoils. Two airfoils with a maximum thickness of 35% were studied, with trailing edge thicknesses of 2% and 10%, respectively.
