– 5.10 – Fig. 5.3 Model test results for Test A (uniform flow with Q B� 0.125 [m 2 s], h ∞ = 18.3 [cm], L = 20 [m], and a logarithmic velocity distribution at the inlet boundary): (a) computed water surface along the channel, (b) computed distributions of the velocity at selected sections, and (c) comparison between computed and measured distributions of the velocity, the eddy viscosity, and the shear stress at the downstream section, x = 19.8 [m].
– 5.11 – Fig. 5.4 Model test results for Test B (developing flow with Q B� 0.125 [m 2 s], h ∞ = 18.3 [cm], L = 38 [m], and a uniform velocity distribution at the inlet boundary, u � Q B h): (a) computed water surface along the channel, (b) computed distributions of the velocity at selected sections, and (c) comparison between computed and measured distributions of the velocity, the eddy viscosity, and the shear stress at half reach of the channel, x = 19.04 [m].
