Abstract

The free-surface flow in the vicinity of a bridge pier positioned normal to a fixed channel bed represents a classical problem of fluvial hydraulics. The present study aims to a realistic two-dimensional numerical modeling of the flow around obstacles such as a cylinder. The depth averaged Navier-Stokes equations describing viscous, unsteady, free-surface flow are solved using an explicit finite- volume numerical scheme in integral form. A grid clustering technique is used in order to form a more dense computational grid in high flow gradients regions. A multi-grid algorithm has been developed to accelerate t
