Combination of experimental and numerical approaches to determine the main characteristics of skimming flow in stepped spillways

RBRH, 2020
The traditional approach for the hydrodynamic characterization of the flow down stepped spillways is through physical modeling, which is susceptible to scale effects and has limitations related to experimental apparatus, laboratory space and the spatial ...

Energy Dissipation on Stepped Spillways [PDF]

Journal of Hydraulic Engineering, 1995
The author provided interesting data on stepped spillway flows. The writer would like to add some information on flow resistance of skimming flows and discuss the energy dissipation on stepped chutes. It will be shown that the author's results are not dissimilar with results previously obtained by other researchers.

Confinement‐Driven CO Spillover in CuAg@MSN Tandem Catalysts Boosts C2 Selectivity Toward Electrocatalytic CO2 Reduction

Advanced Science, EarlyView.
The CuAg@MSN catalyst developed in this study promotes C─C coupling by regulating the coverage of *CO intermediates through spatial confinement effects, significantly enhancing the selectivity of CO2 electroreduction for C2 product formation. ABSTRACT Tandem catalysts represent a promising paradigm for synergistic electrochemical CO2 reduction (CO2RR ...

Step cavity and gabion aeration on a gabion stepped spillway [PDF]

Hydraulic structures and society - Engineering challenges and extremes, 2014
Recent advances in gabion construction techniques have increased the interest for gabion stepped spillways. The present study investigates the air entrainment process in the stepped cavity of a gabion stepped spillway through physical modelling. The microscopic air-water flow characteristics were investigated using a phase-detection probe, complemented
