Investigation of The Area of Around Bridge Abutment by A-Jacks to Protect Against Scour [PDF]

علوم و مهندسی آبیاری, 2017
Scouring is a natural phenomenon that arises from the erosive action of flow field in the alluvial streams. Bridge failure caused by fully scouring of the piers and abutment makes completely clear the necessity of investigating in the case of scour ...

Influence of attack angle on ventilated supercavitating flow at high Froude number condition

Xibei Gongye Daxue Xuebao, 2022
To study the influence of attack angle on ventilated supercavitating flow, a numerical model is established to simulate the supercavitation flow by using the inhomogeneous multiphase flow model and the SST k-ω turbulence model.

The effects of ice-water discharge ratio and flow Froude number on local scour around tandem double piers and ice jam thickness in an S-shaped channel

Journal of Hydrology and Hydromechanics
In cold regions, bridge piers in rivers can alter flow characteristics and influence the formation and evolution of ice jams, complicating the local scour around the piers and the distribution of ice jam thickness.

On a Role of the Interfacial Froude Number

Coastal Engineering 1980, 1980
As already stated in the previous conference, the fresh-water flow which passes through a river mouth horizontally into the sea, exhibits a special characteristic due to the effect of buoyancy. Its dynamics belongs, essentially to the same category with the transonic flow in aerodynamics. The interfacial Froude number plays a dominant role in this case,

Electrical resistance tomography for process intensification of gas–liquid stirred tanks: A comparison of linear back projection and sensitivity conjugate gradient algorithms

The Canadian Journal of Chemical Engineering, EarlyView.
Monitoring gas–liquid dynamics using Electrical resistance tomography for process intensification in stirred tanks Abstract Electrical resistance tomography (ERT) is a non‐invasive technique widely applied to the study of multiphase flows, where phases exhibit different electrical properties.
