, − − simulation of mean wing tip vortex characteristics at x/c = 6 position were compared to experiments. The wing tip vortex was generated by a wing at = 10 , ∞ = 34 ⋅ −1, = 3.22 × 10^5. Star CCM+ CFD solver and a wind tunnel with a five hole probe located at University of Limerick were used. The study is an extension of Dr. O’Regan and Dr. Griffin research, O'Regan et al. (2014). Good results in the mean characteristics were achieved only by LES simulation. RANS simulation predicted faster dissipation of a tip vortex and didn’t capture a jet-like axial velocity in a vortex core position.
