Numerical Study of Flow Pattern in the Bend Channels Affected Parameter U/Uc Using Flow-3D Software

Most rivers have bend routs that the quite complex flow pattern is dominated on them. It is necessary to study the behavior of a river, the flow pattern is well known that the dominant bend. Numerical models as a powerful instrument for the prediction of such areas can provide a good understanding of them. In the present study using three-dimensional numerical model Flow-3D, Parameters of U/Uc the flow pattern at a 90 degree arc of the moving bed is placed. The results were compared with experimental data.Analysis of results relevant to flow pattern in cross sections and different plans are among other points introduced in this paper.
