SINOPSIS
Computations are reported of the flow over a NACA 0012 half-wing with rounded wing tip. The aim is to test the performance of a number of turbulence models in capturing the generation and near-field decay of the strongly accelerated vortex that is shed from the tip. Results using linear and non-linear eddy-viscosity models are presented, but these all exhibit too rapid a decay of the vortex core, and it is only an advanced stress transport model that is shown to reproduce many of the features found in the experimental measurements.
