High Reynolds number Navier–Stokes solutions and boundary layer separation induced by a rectilinear vortex

► We compute Prandtl and Navier–Stokes solutions at high Re. ► Large-scale and small-scale interactions within the boundary layer are revealed. ► Large-scale interaction leads to the failure of Prandtl’s BL theory. ► High gradients and splitting of vortex cores characterize the small-scale stage. ►...
