Evaluating Dynamic Stall-Onset Criteria for Mixed and Trailing-Edge Stall

AIAA Journal, 2022
We evaluate two leading-edge-based dynamic stall-onset criteria (namely, the maximum magnitudes of the leading-edge suction parameter and the boundary enstrophy flux) for mixed and trailing-edge stall. These criteria have been shown to successfully predict the onset of leading-edge stall at Reynolds numbers of [Formula: see text], where the leading ...

Compressibility effects on dynamic stall [PDF]

Progress in Aerospace Sciences, 1996
Abstract Dynamic stall delay of flow over airfoils rapidly pitching past the static stall angle has been studied by many scientists. However, the effect of compressibility on this dynamic stall behavior has been less comprehensively studied. This review presents a detailed assessment of research performed on this subject, including a historical ...

Investigation of dynamic stall onset

Aerospace Science and Technology, 2006
Abstract In a 2003 test campaign in the DLR-VAG test stand unsteady pressure distributions during dynamic stall have been measured on a 2D-wing model with OA312 airfoil section. To investigate the effect of transition on dynamic stall onset different tripping devices have been fixed at the leading edge of the model.

On the influence of blade thickness-to-chord ratio on dynamic stall phenomenon in H-type Darrieus wind rotors

Energy Conversion and Management, 2020
The present work examines the influence of blade thickness-to-chord ratio (t/c) on dynamic stall phenomenon in an H-type Darrieus wind rotor. A 2D incompressible numerical study is conducted on a single-bladed rotor at a tip speed ratio (TSR) of 2 with a
