Experimental Study of the Three-Dimensional Wakes Produced by Trapezoidal Panels with Varying Trailing Edge Geometry and Pitching Amplitude

Three-dimensional characteristics of the jet flows induced by a pitching plate in a quiescent fluid

“…The identified vortex cores in each plane are then interpolated to form 3-D vortex structures. A similar technique was reported in the works by Green et al (2011) and King & Green (2019). Further discussion of this technique is provided in § 4.…”

“…3-D jets induced by a pitching plate 887 A25-3 an opposite-sign interaction with the horseshoe shed immediately after and a like-sign interaction with the horseshoe that follows with 2π phase difference. Green and co-workers (Green & Smits 2008;Green, Rowley & Smits 2011;King & Green 2019) performed 3-D PIV combined with a Lagrangian coherent structure (LCS) analysis on trapezoidal pitching plates in a free stream and provided 3-D graphical representations of the vortex structures in the wake, confirming the aforementioned interactions. Taira & Colonius (2009) used numerical simulations to investigate the transient structures shed from a pitching plate in a free stream starting from rest.…”
