The Influence of Hydrodynamics on Erosion-Corrosion in Two-Phase Liquid–Particle Flow Available to Purchase

Erosion-corrosion measurements on ferrous materials in CO₂ and sand-containing formation water are correlated with hydrodynamic measurements applying laser Doppler anemometry. It is shown that in disturbed flows (tube with constriction) maxima of mass-loss rates correspond to turbulent fluctuations of the radial flow component. Parameter studies on flow velocity, flow geometry, particle concentration, and particle size yield correlations that can be represented by power laws between mass-loss rates and the corresponding variable. The distinction between the erosive and errosion-corrosive component of the attack is possible by choosing media that are either pure erosive or pure corrosive. For the tube flow, the results from mass-loss measurements can be explained on the basis of the radial component of the kinetic energy of the particles.
