Finite-volume Method for Modelling Shallow Water Flows in Presence of External Forces
نویسندگان
چکیده
The numerical method for study of hydrodynamic flows over an arbitrary bed profile in the presence of external force is proposed in this paper. This method takes into account the external force effect, it use the quasi-two-layer model of hydrodynamic flows over a stepwise boundary with consideration of features of the flow near the step. There are performed the numerical simulations based on proposed algorithm of various physical phenomena, such as a breakdown of the rectangular fluid column over an inclined plane, the large-scale motion of fluid in the gravitational field in the presence of Coriolis force over an underlying mountain-like surface. Computations made for two dimensional dam-break problem on slope precisely conform to laboratory experiments. Kirill V. Karelsky, Arakel S. Petrosyan and Alexander G. Slavin

Quasi-two-layer finite-volume scheme for modeling shallow water flows with the presence of external forces
Finite-volume numerical method for study shallow water flows over an arbitrary bed profile in the presence of external force is proposed. This method uses the quasi-twolayer model of hydrodynamic flows over a stepwise boundary with advanced consideration of the flow features near the step. A distinctive feature of the suggested model is a separation of a studied flow into two layers in calculat...

متن کاملProjection finite volume method for shallow water flows
A simple and accurate projection finite volume method is developed for solving shallow water equations in two space dimensions. The proposed approach belongs to the class of fractional-step procedures where the numerical fluxes are reconstructed using the method of characteristics, while an Eulerian method is used to discretize the conservation equations in a finite volume framework. The method...

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...
