Analysis of the implementation of a three-dimensional hydrodynamic model in the flow of a natural channel

Abstract:

In the analysis of river hydrodynamics a great quantity of variables are present, this variables when considered in solving the state equations describe the flow behavior. In this work is presented the three- dimensional solution of the equations of Navier Stokes averaged by Reynolds with a model of closing for the turbulence K-xi; solution applied in the flow of the river Tercero or Ctalamochita in the province of Cordoba, Argentina. The calculation tool for solving equations of state is the SSIIM model, a free software oriented to the computational fluid dynamics developed at the Norwegian University of Science and Technology. The importance of analyzing the flow in three-dimensional form contrasts with the difficulty of their numerical solution, therefore was described the SIMPLE algorithm applied in this work for the solution of the equations of state.
