Abstract

Spur dikes are river training structures used for prevention of erosion at river banks and cause distancing of flow from the critical zone and creation of local contraction in water flow. In the present study, 2D modeling of the flow pattern around a spur dike in a straight canal with 6m length and 0.45m width is presented. Also the finite element method is utilized for solving the differential equations. Modeling of the turbulent flow around a single spur dike is performed using k-ε model in ANSYS software and the results were compared to those of the experimental study. The results show that the finite element method, by incorporating the k-ε model, models the flow pattern around the spur dike well and yields an average error value of 12.57%, and this shows a good agreement between the numerical modeling results and those of the experimental study.
