Effect of vortex shedding in unsteady aerodynamic forces for a low Reynolds number stationary wing at low angle of attack

- Elucidated the relation between wake vortex shedding and aerodynamic force fluctuations for a wing
- Instantaneous forces during a shedding cycle obtained from time resolved particle image velocimetry
- Time evolution of Instantaneous pressure fields and vortical structures around the wing resolved during a shedding cycle.
- Vortex shedding results in a periodic lift and drag variation during a cycle as shown by POD and PSD analysis.
- A six step model describing the vortex-force relation is proposed.
