Closure to “Air demand prediction and air duct design optimization method for spillway tunnel”

where Co is the so-called choking number (Crispino et al., 2019; Stahl & Hager, 1999), F the approach Froude number, Y∗ = Ht/h0 the sequent depth ratio for pressurized flows for a rectangular tunnel, Ht the tunnel height and h0 the water depth. When Eqs (1) and (2) are applied, the detailed parameters of the spillway tunnel of Jinping-I dam are listed in Table C1, in which s is the gate opening percentage, hgate the height of gate opening, hc the water depth of the contraction section downstream the gate (Henry, 1977), B the tunnel width, Hteq = A/B the equivalent tunnel height and A ≈ 206m2 the sectional area Figure C1 Comparison of β: (a) prototype observations, (b) Eq. (1), (c) the model of the original article

期刊介绍： The Journal of Hydraulic Research (JHR) is the flagship journal of the International Association for Hydro-Environment Engineering and Research (IAHR). It publishes research papers in theoretical, experimental and computational hydraulics and fluid mechanics, particularly relating to rivers, lakes, estuaries, coasts, constructed waterways, and some internal flows such as pipe flows. To reflect current tendencies in water research, outcomes of interdisciplinary hydro-environment studies with a strong fluid mechanical component are especially invited. Although the preference is given to the fundamental issues, the papers focusing on important unconventional or emerging applications of broad interest are also welcome.
