A complementary numerical and experimental study of the influence of Reynolds number on theoretical models for wingtip vortices

On the linear receptivity of trailing vortices

“…Similarly, experiments and implicit large eddy simulation (iLES) of García-Ortiz et al. (2019, figure 6 b ) report a range of roughly over a streamwise range of 40 chords and chord Reynolds number . For these representative values of departure from a Gaussian vortex is essentially negligible.…”

Influence of passive deformation in the lift coefficient of a NACA0012 wing model

“…Finally, there is also a weak influence of the down-wash effect because the wing model is at a finite distance from the wall of the wind tunnel. Previous Particle Image Velocimetry measurements showed a non-dimensional core radius, r core /c, of trailing vortices ranging between 0.07 and 0.12 in the near and intermediate fields at z/c ≤30 from the non-deformed NACA0012 wing model for Re=20-40×10 3 with sAR=2 [27,28]. The reader must consider that the larger Re, the smaller the core radius of the trailing vortex [28].…”

Developments in Wingtip Vorticity Mitigation Techniques: A Comprehensive Review

“…The phenomenon of wingtip vortices has captivated researchers for many decades in their attempts to minimize their harmful effects. Researchers have made extensive experimental and theoretical studies [29][30][31][32][33][34][35] as well as numerical investigations [29,[35][36][37][38][39][40][41] to understand the characteristics of wing tip vortices. To mitigate the adverse effect of wingtip vorticities, many wingtip devices have been proposed over the years with varying degrees of success.…”
