Figure 3. Velocity vertical profiles at different phases (a) and bottom shear stress time evolution (b) computed by DNS (. . .), the original Wilcox transitional k-w model (- -) and the new k-w model (—) for a sinusoidal outer flow U = U0 sin(2pt/T ) with T = 4 s, U0 = 1.1 m/s over a smooth bottom (Rd = 1241, Re = 7.7 105).
