WITHDRAWN: Numerical investigation of fluid flow simulation through a cylindrical shape orifice flow meter using Ansys-fluent software

Abstract Orifices are typical flow meter used to measure fluid flow in industrial pipe work. The choice of an appropriate standard K-epsilon turbulence model is critical for achieving acceptable flow measurement accuracy in numerical simulations. This work offers a numerical investigation of fluid flow simulation in a cylindrical orifice using Ansys-fluent with turbulence modeling. It is used for continuous and incompressible flows. The computations were performed in three-dimensional axisymmetric flow, and the governing equations of the flow were determined using continuity and Navier-Stokes equations (NSEs). Furthermore, the simulation results in terms of velocity and pressure profiles are determined. Finally, CFx-Post simulations were used to determine the position of the vena contracta. The location and position of the vena contracta reveal that as the area ratio increases, the location of the vena contracta changes towards the orifice.
