Comparison of the Reynolds stresses between the full LES (tripped), the RANS simulation (modeled), and zonal LES II (based on the RANS data) at the inflow of the zonal LES. The used values for the scaling tensor S_ij are S₁₁ = 0.9, S₂₂ = 0.45, S₃₃ = 0.65 and S₁₂ = 0.3. The area where the ALF is applied is indicated in blue.
