RISFast 3D Simulation of Nonhydrostatic Flows Using a Modified Ghost-Cell Free-Surface Pressure Treatment
Publisher: ASCE
Abstract: Treatment of the free-surface pressure boundary (FSPB) remains a challenge for the three-dimensional (3D) nonhydrostatic hydrodynamic models using a vertical staggered-grid variable arrangement. Through the tests of the ...
Flux-Form Eulerian-Lagrangian Method for Solving Advective Transport of Scalars in Free-Surface Flows
Publisher: American Society of Civil Engineers
Abstract: A two-dimensional (2D) flux-form Eulerian-Lagrangian method (FFELM) on unstructured grid is proposed for solving the advection equation in free-surface scalar transport models. The scalar concentrations of backtracking ...
Three-Dimensional Simulation of Scalar Transport in Large Shallow Water Systems Using Flux-Form Eulerian–Lagrangian Method
Publisher: ASCE
Abstract: This study is devoted to advancing hydroenvironmental modeling of large-scale shallow water systems to the times of three-dimensional (3D) simulations, where the solution of advective transport of scalar is the focus. The ...
