An investigation into vortex growth and stabilization for two-dimensional plunging and flapping plates with varying sweep
A simple analytical model for leading-edge vortex (LEV) growth is proposed and tested,
based on the transport of vorticity-containing mass through the shear-layer. The two-
dimensional case is validated using time-resolved Particle Image Velocimetry. As a
precursor to developing a model for finite wings, the effect of varying spanwise flow on a
nominally two-dimensional profile is investigated by imposing plunging and flapping
motions on high aspect-ratio flat-plate profiles of sweep angles Λ=+ 45°,− 45° and 0°. By …
