Carbon capture and storage (CCS) is a critical strategy in global efforts to mitigate climate change. A key component of CCS is the safe and efficient pipeline transport of carbon dioxide (CO₂), which often contains impurities—most notably water. The presence of water in the CO₂ stream can result in two-phase flow, increasing the risk of internal pipeline corrosion. Corrosion is minimized when water remains fully entrained as dispersed droplets within the continuous CO₂ phase. However, when water separates and forms a settled layer along the pipe wall, corrosion becomes severe. This study investigates the conditions that govern water distribution across the pipe cross-section. A mechanistic model is developed to evaluate the interplay between hydrodynamic forces, operating conditions, and pipe wall wettability. The results provide criteria for predicting entrainment or deposition behavior of the water phase, with implications for corrosion risk assessment and pipeline design in CCS applications.
