Numerical Simulation of open channel flow using the Saint Venant Equations and the Method of Characteristics

Abstract

The computational modeling of fluid behavior has been established as a Hydraulic Engineering design tool through the years to optimize the way in which men deal with water resources problems. Among these problems, the unsteady open channel flow simulation [...]

Transient large heat advection in fractured rock: a zero-thickness interface formulation

Abstract

Two of the main mechanisms of heat transport in engineering problems are diffusion and advection. In a FEM context it is well known that if advection dominates over diffusion (Péclet number Pe > 1), traditional Galerkin formulations may lead to oscillatory results [1], although [...]

An algorithm for the design of a feedforward controller in canals

Abstract

When it is carried out any movement of a gate or another mechanism of control of a canal in free surface flow, an answer of the flow can take a lot of time in being noticed in the place of the canal takes place in which it was generated the necessity to increase or to reduce the irrigation [...]

Inverse Dynamics of Geometrically Exact Beams

Abstract

This paper is concerned with the inverse dynamics of flexible mechanical systems whose motion is governed by quasi-linear hyperbolic partial differential equations. Problems that appear by applying classical solution strategies to the problem at hand, e.g. integrating the problem [...]

Mathematical model simulating the Slurry Pipeline in pressurized conduits

Abstract

International audience; Numerous slurry transportation pipeline systems have been built in the past 10 years. At the same time, T. Chakkour & F. Benkhaldoun study in [1] the hydraulic transport of particles in tubes. We investigated in [2] the hydraulic transport of slurry system [...]

Pressure Transient Model of Water-Hydraulic Pipelines with Cavitation

Abstract

Transient pressure investigation of water-hydraulic pipelines is a challenge in the fluid transmission field, since the flow continuity equation and momentum equation are partial differential, and the vaporous cavitation has high dynamics; the frictional force caused by fluid viscosity [...]
