Maximum Flow Intensities at Tools for Measuring Flow Influenced Corrosion

The maximum ‚freak’ energy densities [Pa] were quantified for disturbed one- and two-phase flow regimes typically encountered  in one- and two-phase (gas-pulsed) submerged jet flow, one-phase rotating cage and in slug flow regimes. Correlations exist between maximum ‘freak’ energy densities and corresponding wall shear stresses [Pa]. The correlation coefficients depend, however, on the nature of the corrosion system and are influenced e.g. by the presence of functional chemicals. Clear correlations were found between maximum ‘freak’ energy densities and corrosion rates and are exemplified by results of steel corrosion in uninhibited and inhibited CO₂ containing brine.
