A Spectral Finite-Volume Method for the Shallow Water Equations

A spectral finite-volume (SFV) method is proposed for the numerical solution of the shallow water equations. This is the first phase in the development of a layered (isopycnal) ocean model. Its target applications include, in particular, the simulation of the wind-driven oceanic circulation in geometrically complex basins where layer outcropping and/or isopycnal–bathymetry intersection must be ...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

A Finite Volume Multilevel Approximation of the Shallow-water Equations

Abstract. We present a multilevel method which is based on a central-upwind finite volume deiscretization and uses new incremental unknowns which enable to preserve the numerical conservation of the scheme. The method is applied to the nonviscid twodimensional shallow-water equations, it is tested and analyzed on two and three levels of discretization on different test cases and turns out to fu...

Error Estimates on the Approximate Finite Volume Solution of Convection Diffusion Equations with General Boundary Conditions

We study here the convergence of a nite volume scheme for a diiusion-convection equation on an open bounded set of IR d (d = 2 or 3) for which we consider Dirichlet, Neumann or Robin boundary conditions. We consider unstructured meshes which include Vorono or triangular meshes; we use for the diiusion term an \s points" (where s is the number of sides of each cell) nite volume scheme and for th...
