An advanced Large Eddy Simulation (LES) technique with high accuracy and resolution is proposed with the Approximated Deconvolution Method approach, the generalized characteristic interface conditions, and the generalized Navier-Stokes boundary conditions. Several applications to flows around 2-D NACA0012 aerofoil are presented and discussed. Numerical results show that this method can capture the laminar to turbulent transition phenomena in the order of Reynolds number of 106. In order to validate the present LES technique in more detail, the results are compared with existing wind-tunnel experiments and linear stability analyses with the eN method and discussed.
