摘要：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 CI- 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 CI- ions which are concentrated at the bend position play a role in that.
