Experiment on Free Overfall Measuring Flume in Rectangle Canal
工程科学与技术, 2015 :In open channels, free overfall is a situation where the flow separates from the rigid bed to form a free nappe due to a sudden drop in the channel bed, the relationship of the end-depth to the critical depth is constant, it could be used as a simple ...

Nappe Vibration Mitigation Techniques for Free-overfall Structrures
, 2016 peer reviewedNappe vibration is a phenomenon that has been witnessed in the field for a variety of different free overflow hydraulic structures operating at low heads, such as fountains, crest gates, and weirs.

Études expérimentale et numérique de l’influence d’un jet plan pariétal sur une nappe de retour
, 2011 The aim of this study is to determine the influence of a wall attached plane jet on the backlayering. This study is composed of two parts. The experimental part consists in identifying the behaviour of the backlayering in presence of the jet.

Numerical and experimental investigation of a confined plunging liquid jet system [PDF]
, 2012 In a confined plunging liquid jet (CPLJ) system, a liquid jet is allowed to fall in a partially submerged narrow downcomer tube. Liquid jet impingement at gas-liquid interface leads to entrainment of gas, which is dispersed down the downcomer tube in to ...

Demystifying the discharge coefficient for flow over thin weirs and sills
FlowA revised derivation of the discharge coefficient for flows over thin weirs and sills in the limits of wall overflow to a free overfall is given. Using dimensional analysis, we show that the discharge coefficient, $C_{d}$ , in the classical weir ...

Effect of Nappe Non-aeration on Caisson Sliding Force during Tsunami Breakwater Overtopping
, 2017 The sliding force was a contributing factor to the displacement of caissons from the Kamaishi composite breakwater during the Great East Japan tsunami 2011 (Arikawa et al., 2012).
