a Mean velocity, u+, as function of y+. The black dotted line represents the DNS reference at Reτ = 5200. The red, blue and green triangles are NNPC-LBM results at Reτ = 1000, 2000, 5200 respectively. b \({\left\langle {u}^{{\prime} }{v}^{{\prime} }\right\rangle }^{+}\) as function of y/δ. The red, blue and green dotted lines are DNS reference at Reτ = 1000, 2000, 5200. The red and blue triangles and the green dots are NNPC-LBM results at Reτ = 1000, 2000, 5200 respectively.
