Abstract
numbers 10 4 , 10 5 and 10 6 . The code used was fluent v6.3, where the Navier-Stokes equations are solved by the finite volume method with k-e like a turbulent model. Validation of numerical predictions for the velocity profiles, turbulence intensity and the gyration angle of the fluid is made according to ISO 5167. The results obtained show the effectiveness of the perforated plate in the development and the establishment of the turbulent flows towards the fully developed pipe flow wish is a necessary condition for flow measurement accuracy. We also note, from the results, that the flow needs more 30D of distance to reach better metrological performances.
