Abstract

The project aims to develop general use computer programs and the respective software for drainage modeling and for the transporting of contaminants in natural and artificial waterways. The products from this project should solve, in a general way, continuity equations, Navier-Stokes equations, Reynolds equations, transportation equations with turbulence parameters and transport equations of other scales. The solutions will be applied to systems of Cartesian coordinates both 2- and 3-dimensional, 2-dimensional Polar coordinates and 3-dimensional Cylindrical coordinates. These solutions will be generated through alternated grids (movement quantity grid) both uniform and non-uniform. The methods of primitive variables and finite volumes will be used. The solutions will be seek to simulate and to forecast incompressible outflow and variable density outflow, permanent and non-permanent outflow, turbulence and non-turbulence, regular and non-regular domains, the consideration of bed variations and coastline variations and elevation of surface water.
