Integral Equation Model for Wave Propagation with Bottom Frictions
Publisher: American Society of Civil Engineers
Abstract: An integral equation method is developed to calculate wave propagation and runup in a two‐dimensional wave channel. First, the problem is formulated as a potential flow with nonlinear free‐surface boundary conditions. The ...
Well-Balanced Scheme between Flux and Source Terms for Computation of Shallow-Water Equations over Irregular Bathymetry
Publisher: American Society of Civil Engineers
Abstract: Although many numerical techniques such as approximate Riemann solvers can be used to analyze subcritical and supercritical flows modeled by hyperbolic-type shallow-water equations, there are some difficulties in practical ...
Weighted Averaged Flux-Type Scheme for Shallow-Water Equations with Fractional Step Method
Publisher: American Society of Civil Engineers
Abstract: A numerical model describing two-dimensional fluid motions has been developed on an unstructured grid system. By using a fractional step method, a two-dimensional problem governed by the two-dimensional shallow-water ...
Numerical Simulation of Shallow-Water Flow Using a Modified Cartesian Cut-Cell Approach
Publisher: American Society of Civil Engineers
Abstract: The Cartesian cut-cell method can be used to represent irregular and complex computational domains with less computational efforts by cutting the grid cells on the boundary surfaces in a background uniform Cartesian mesh. ...
Using Inclined Walls to Control the Bottom Shear Stress Distribution in an Annular Flume
Publisher: American Society of Civil Engineers
Abstract: This study proposes a method to alter secondary flow pattern in a rotating annulus flume and obtain a resulting uniform bottom shear stress distribution along the radial direction by changing the shape of the channel cross ...
