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.

Exponential asymptotics and gravity waves [PDF]
, 2006 The problem of irrotational inviscid incompressible free-surface flow is examined in the limit of small Froude number. Since this is a singular perturbation, singularities in the flow field (or its analytic continuation) such as stagnation points, or ...

Experimental analysis of hydraulic jump at high froude numbers [PDF]
Sādhanā, 2021 Abstract The hydraulic jump is a rapid transition state from supercritical to subcritical flow that occurs commonly in rivers, prismatic channels and downstream of spillways. In this study, the characteristics of the hydraulic jump in a stilling basin downstream of the spillway chute channel with the slopes of α = 12o and 30o were investigated ...

Non-continuous Froude number scaling for the closure depth of a cylindrical cavity [PDF]
, 2006 A long, smooth cylinder is dragged through a water surface to create a cavity with an initially cylindrical shape. This surface void then collapses due to the hydrostatic pressure, leading to a rapid and axisymmetric pinch-off in a single point ...

Heave and pitch motions in shallow water including the effect of forward speed [PDF]
, 1977 The problem of small heave and pitch motions of a slender ship in shallow water including the effect of forward speed is analysed using the method of matched asymptotic expansions. Formulae valid to first order in slenderness are given for the added-mass

On the Two-point Correlation of Potential Vorticity in Rotating and Stratified Turbulence [PDF]
, 2006 A framework is developed to describe the two-point statistics of potential vorticity in rotating and stratified turbulence as described by the Boussinesq equations.
