The maximum ”freak” energy densities (FED) [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. Good correlations were found between FEDs and corrosion rates exemplified by results of steel corrosion in uninhibited and inhibited CO2 containing brine.

Key words: flow induced localized corrosion (FILC), jet impingement, gas-pulsed jet, rotated cage, slug flow, functional chemicals, single-phase flow, two-phase flow, CO2 corrosion, freak energy density (FED), wall shear stress, correlation coefficients

The effect of fluid flow on corrosion, or flow accelerated corrosion, is defined by mass transfer and wall shear stress parameters existing in the water phase contacting the solid wall. Jet impingement offers an experimental method to measure the effect of these parameters on corrosion.
