Dynamic stall reattachment revisited
Sahar Rezapour, Karen Mulleners
Dynamic stall on airfoils is an undesirable and potentially dangerous phenomenon. The motto for aerodynamic systems with unsteadily moving wings, such as helicopters or wind turbin…

Dynamic Stall Characteristics and Modelling of Time-Varying Pitching Kinematics
Sahar Rezapour, Karen Mulleners
We present an experimental investigation examining how the complexity of pitching kinematics influences dynamic stall characteristics, including the stall delay and aerodynamic for…

Highly deformable flapping membrane wings suppress the leading edge vortex in hover to perform better
Alexander Gehrke, Karen Mulleners
Airborne insects generate a leading edge vortex when they flap their wings. This coherent vortex is a low pressure region that enhances the lift of flapping wings compared to fixed…
