The corrosion properties of AISI 316L stainless steel in upward slug flow were initially investigated using the electrochemical measurements and computational fluid dynamics (CFD) simulations. The results demonstrate that the slug flow may destroy the passivation film on the specimen surface due to its intermittency and volatility, accelerating the pitting corrosion process on the electrode surface. It results in a higher corrosion rate in the two-phase slug flow than in the single-phase flow. The variations of superficial velocity lead to changes in the slug flow configuration. The variation has a greater impact on the Taylor bubble than the liquid slug. The changes in slug flow configuration result in differences in shear stress and mass transfer coefficient, leading to corresponding differences in electrochemical properties of AISI 316L stainless steel.

最初使用电化学测量和计算流体力学（CFD）模拟研究了AISI 316L不锈钢在上弹流中的腐蚀性能。结果表明，团状流可能会由于其间断性和挥发性而破坏试样表面的钝化膜，从而加速电极表面的点蚀过程。与单相流相比，两相塞流中的腐蚀速率更高。表面速度的变化导致团状流形态的变化。该变化对泰勒气泡的影响大于液体团块。团状流形态的变化导致剪切应力和传质系数的差异，
