Effect of 3D stall‑cells on the pressure distribution of a laminar NACA64‑418 wing

A 3D stall-cell flow-field has been studied in a 4.8 aspect-ratio wing obtained by linear extrusion of a laminar NACA64-418 airfoil profile. The span-wise change in the velocity and pressure distribution along the wing has been quantified with respect to the development of cellular structures from 8◦ to 20◦ angle of attack. Oil-flow...

Point vortex modelling of the wake dynamics behind asymmetric vortex generator arrays

In this work, we present a simple inviscid point vortex model to study the dynamics of asymmetric vortex rows, as might appear behind misaligned vortex generator vanes. Starting from the existing solution of the in_nite vortex cascade, a numerical model of four base-vortices is chosen to represent two primary counter-rotating vortex pairs and...
