Using side flow jets as a scour countermeasure downstream of a sluice gate
Beni-Suef University Journal of Basic and Applied Sciences, 2021 Background Local scour is one of the main problems affecting the stability and operation of control hydraulic structures. Many techniques were used to control the resulting scour.

Numerical Simulation on the Local Scour Processing and Influencing Factors of Submarine Pipeline
Journal of Marine Science and Engineering, 2023 To investigate the different influencing characteristics of local scour around submarine pipelines, hydrodynamic and sediment transport two-dimensional models based on Flow-3D are used to numerically simulate the local scour around the pipeline under ...

Localized Turbulent Flows on Scouring Granular Beds [PDF]
Physical Review Letters, 2005 In many applications a sustained, localized turbulent flow scours a cohesionless granular bed to form a pothole. Here we use similarity methods to derive a theoretical formula for the equilibrium depth of the pothole. Whereas the empirical formulas customarily used in applications contain numerous free exponents, the theoretical formula contains a ...

Local scour around a bridge pier under ice-jammed flow condition – an experimental study
Journal of Hydrology and Hydromechanics, 2021 The appearance of an ice jam in a river crucially distorts local hydrodynamic conditions including water level, flow velocity, riverbed form and local scour processes.

Local scour around two pipelines in tandem in steady current
, 2014 In this study, local scour around two identical pipelines in a tandem arrangement are investigated numerically. Two-dimensional Reynolds-averaged Navier-Stokes (RANS) equations are solved for simulating the flow around the pipelines and the conservation ...

Experimental investigation of local scour around multi-vents bridge piers
Alexandria Engineering Journal, 2015 The harmful effect of local scour around bridge piers and abutments can induce high maintenance costs or even bridge collapse resulting in the disturbance of traffic and possibly human losses.

Numerical investigation of wave-induced local scour around a submarine pipeline
, 2014 A two-dimensional numerical model is developed in this work to predict the local scour around subsea pipelines induced by the orbital fluid motion due to free-surface water waves. Instead of being simplified as an oscillatory flow, the motion of the wave

Advanced Materials Interfaces, EarlyView.This study develops a self‐cleaning solar evaporator based on MXene‐coated aramid nanofiber aerogels for efficient desalination under high‐salinity conditions. The cylindrical evaporator combines strong photothermal conversion, capillary water transport, and self‐rotation triggered by salt accumulation.
