Numerical Simulation of Dispersed Phase Flow in a Tube Considering Bubbles Erosion and Cl- Ions Concentration Effects
It is found that the tube damage is caused by two induced factors: bubbles erosion as a dispersed phase and chemical composition of water rich in Cl- ions that result in loss of stability of protective oxide layer. The tube is subject to be erosion–corrosion in a given set of conditions, using numerical simulation techniques. The results prove to be erosion–corrosion effects owing to turbulence, bubbles dynamics affect and ensuing erosion rates. In addition, the bulk of Cl- ions which are concentrated at the bend position play a role in that.
