Simulation of turbulent flow of a rotating cylinder electrode and evaluation of its effect on the surface of steel API 5L X-56 during the rate of corrosion in brine added with kerosene and H₂S

This work is based on the simulation, through ANSYS Fluent software, of turbulent flow induced by a rotating cylindrical electrode. It was carried out a 2-D Hydrodynamic simulation using the standard turbulence models k-ε and k-ω, the results on the velocity field clearly show the formation of turbulent Taylor vortex flow. The flow accelerated corrosion rate effect on the surface of the API 5L-X56 Steel was assessed using a brine of kerosene and H2S. Corrosion products formed were characterized with Scanning Electron Microscopy (SEM), Electron Dispersive X-ray (EDX), X-ray Diffraction (XRD) and Linear polarization technique. XRD analysis showed that the corrosion products are mainly composed of a mixture of oxides and sulfides.
