Comparison of Cell-centered and Node-centered Formulations of a High-resolution Well-balanced Finite Volume Scheme: Application to Shallow Water Flows
نویسندگان
چکیده
We present numerical comparisons for the simulation of unsteady 2D shallow water flows over topography with wet/dry fronts, between well-balanced cell-centered and node-centered formulations of a finite volume high-resolution algorithm. In both formulations we utilize Roe’s Riemann solver, while second-order spatial accuracy is achieved with MUSCL-type reconstruction techniques. Grid refinement studies are emphasized.

A Mass Conservative Method for Numerical Modeling of Axisymmetric flow
In this paper, the cell-centered finite volume method (CC-FVM) has been presented to simulate the axisymmetric radial flow toward a pumping well. The model is applied to the unstructured triangular grids which allows to simulate inhomogeneous and complex-shaped domains. Due to the non-orthogonality of the irregular grids, the multipoint flux approximation (MPFA) methods are used to discretize t...
متن کاملAn efficient unstructured MUSCL scheme for solving the 2D shallow water equations
The aim of this paper is to present a novel monotone upstream scheme for conservation law (MUSCL) on unstructured grids. The novel edge-based MUSCL scheme is devised to construct the required values at the midpoint of cell edges in a more straightforward and effective way compared to other conventional approaches, by making better use of the geometrical property of the triangular grids. The sch...

The aim of this paper is to present a new well-balanced finite volume scheme for two-dimensional multilayer shallow water flows including wet/dry fronts. The ideas, presented here for the two-layer model, can be generalized to a multilayer case in a straightforward way. The method developed here is constructed in the framework of the Finite Volume Evolution Galerkin (FVEG) schemes. The FVEG met...
