Corrosion is affected in different ways by the flowing fluids depending on solution- metal interface. To study these phenomena, there are some equipments in laboratory which allow to simulate field conditions by using correlations that can predict mass transfer and shear stress coefficients. However, these correlations have not been validated for all systems and there are no expressions to describe corrosion rates as a function of such parameters. The limit current technique was used to determine the mass transfer and shear stress on the wall, which were compared to those predicted by correlations for an impingement cell; besides, the corrosion rates for different experimental conditions were evaluated. The corrosion mechanism was found to be controlled partially by charge and mass transfer, so not all correlations fitted experimental data. Finally, from the main electrochemical variables, a mathematical correlation of corrosion rate, hydrodynamic variables and mass transfer was obtained.
