Implicit Large Eddy simulations of turbulent flow around a square cylinder at Re=22,000

•The Implicit LES approach with 2nd and 3nd order WENO scheme is applied to square cylinder flow at Re=22000.•The near wall performance of 3rd order WENO ILES is comparable to conventional LES with WALE model and out-performs LES with dynamic Smagorinsky model.•Both LES and ILES face challenge in te...
