The Rotating cage technique is used to evaluate corrosion inhibitors. The rotating cage holds 8 coupons containing corrosive liquid, which rotate within it. These coupons have a dynamic that simulates the conditions in a pipe through a corrosive fluid, in this case the material used in pipelines are analyzed oil. A study of the fluid dynamics through the ANSYS software shows that the velocity fields, contours, vectors and speed profiles for symmetric geometries arrangements 2, 4 and 8 embedded specimens with a corrosion inhibitor. The conditions are calculated velocity profiles are standard temperature and solution viscosity of 1.0 cp and 1.5 cp. The density is considered constant of 998 kg / m3 and three angular velocities (920, 460 and 230 rpm) were analyzed. Finally the results of these conditions have been analyzed, yielding values close to zero in the outside walls of the cylinder. The cylinder contain the coupons rotating speeds to ensure turbulence (1) and to analyze the rate of corrosion inhibitor.
