The spatial and temporal evolution of a single 3D tip vortex is simulated with the remeshed vortex method. The flow conditions correspond to the tip vortex generated by the rectangular NCA0012 wing with an incidence angle of 5 degrees and the Reynolds number of 530,000. The simulation begins at 5 and ends at 35 chordlengths downstream the wing. The vorticity at the inlet is time independent and determined according to measurement data. A source box is disposed in front of the inlet to realise the vortex inlet boundary condition. The obtained tangential velocity and axial velocity profiles show little diffusion and dissipation. The vortex core parameters correlate well with the experimental measurements for all positions (from 5 to 30 chordlengths downstream the wing).
