Lukerchenko, Nikolai, Auteur ; Vlasak, Pavel, Auteur ; Chara, Zdenek, Auteur |This paper deals with bed load transport and the movement of rotating spherical particles in an open channel flow is considered. A numerical model for the random process of the particle impact and rebound from the channel bed is developed. Stoch[...]

Yueling Wang, Auteur ; Liang, Qiuhua, Auteur ; Kesserwani, Georges, Auteur |Dam-break flows usually occur in domains with complex geometric and topographic features and involve abrupt flow patterns. A dam-break model must therefore be able to effectively handle different flow types including transcritical flows or hydra[...]

Koftis, T. H., Auteur ; Prinos, P., Auteur ; Koutandos, E., Auteur |Wave interactions with a fixed floating breakwater (FB) are investigated both numerically and experimentally. Laboratory experiments of large scale have been performed in the CIEM flume of the Catalonia University of Technology, Barcelona and me[...]

Anastasios I. Stamou, Auteur ; Demetrios G. Chapsas, Auteur ; George C. Christodoulou, Auteur |A 3-D CFD model based on the Volume of Fluid (VOF) method to calculate the free surface was used to study supercritical flow in gradual open channel expansions. The model was first applied to a modified Rouse expansion, for which extensive exper[...]

Subhasish Dey, Auteur ; Barbhuiya, Abdul Karim, Auteur |Experiment was conducted in a laboratory flume to measure the 3D turbulent flow field by an acoustic Doppler velocimeter in a scour hole at a 45o wing-wall abutment under a clear water regime. The profiles of time-averaged velocity components, t[...]

Tim Fischer-Antze, Auteur ; Nils Ruther, Auteur ; Nils R. B. Olsen, Auteur |A fully three-dimensional non-hydrostatic model was applied to compute the water flow and morphodynamic processes in a laboratory flume. The experiments provided data for bed deformation and grain sorting processes in a 180° channel bend. The da[...]

Jie Zeng, Auteur ; George Constantinescu, Auteur ; Weber, Larry, Auteur |The validation and application of a model to solve for the flow, the sediment transport, and bed morphology changes in open channels is discussed. The non-hydrostatic model solves the three-dimensional (3D) incompressible, Reynolds-Averaged Navi[...]

Crespo, A. J. C., Auteur ; Dalrymple, R. A., Auteur ; Gomez-Gesteira, M., Auteur |The interaction between a large wave and a coastal structure is studied with a 3D SPH model. The role of protecting barriers (dikes and seawalls) to mitigate the force and moment exerted on the structure is analyzed in terms of the dike height a[...]

Mohammad Sedghi-Asl, Auteur ; Hassan Rahimi, Auteur |In this paper, the concept of Darcy–Weisbach's friction loss in pipe flows is employed and combined with Manning's widely used formula in open-channel flow problems to obtain a new relation for flow in porous rockfill media. A new formula to det[...]

Alberto Carlos De Melo Lima, Auteur ; Harry Edmar Schulz, Auteur ; John S. Gulliver, Auteur |Air concentration measurements performed along the lower nappe of a bottom aerator through the impact and downstream flow regions permitted the calculation of air entrainment along the jet length. The air uptake was also measured in the air supp[...]

Murzyn, F., Auteur ; Mouazé, D., Auteur ; Chaplin, J. R., Auteur |Following previous experimental works (Mouaze et al., J. Fulids Engng. ASME 127(6) (2005) 1191–1193; Murzyn et al., Int. J. Multiphase Flow, 31(1), (2005) 141–154) on gas fraction characterisation in hydraulic jumps, the present paper aims to in[...]

Wang, Xiaoming, Auteur ; Liu, Philip L. F., Auteur |The 2004 Sumatra earthquake and the associated tsunamis are one of the most devastating natural disasters in the last century. Several fault plane models have been suggested to represent the rupture mechanism of the earthquake. During this tsuna[...]

Gonzalez, Carlos A., Auteur ; Masayuki Takahashi, Auteur ; Chanson, Hubert, Auteur |On a spillway chute, a stepped design increases the rate of energy dissipation on the chute itself and reduces the size of a downstream energy dissipater. Up to date, the effects of step roughness on the flow properties remain unknown despite th[...]
