  The goal of the present work is to perform a systematic study of the
formation of wing-tip vortices and their interaction with and impact on the
surrounding flow in more details. Of particular interest is the interaction of
these vortices with wall turbulence and the turbulent wake. This is done by
considering two wing geometries, i.e., infinite-span (periodic) and
three-dimensional (wing-tip) wings, at three different angles of attack:
$\alpha=0^o$, $5^o$, $10^o$. Simulations are performed by the high-order
incompressible Navier-Stokes solver Nek5000 with added adaptive mesh refinement
(AMR) capabilities developed at KTH.
