Behavior of the fluid in relation to the geometry of the system is of great interest in piping systems due to the erosion-corrosion and heat transfer phenomena. This paper deals with computation of flow through a two dimensional, symmetric constriction of an incompressible Newtonian fluid in turbulent state using two commercial finite element and finite volume codes, namely COMSOL MULTIPHYSICS and FLUENT respectively. Computation has been performed in order to determine axial and radial velocities at different position with both of these simulators in order to compare finite element and finite volume results in a practical system. In order to assess the accuracy of the findings of the present study, the results have been compared with the experimental data. The results of the present study reveal that the standard k-ε model could be applied safely in such geometries for predicting the flow behavior. Also, results shows that using finite element methods gives more compatible results with experimental data.
