Previous works on the oil/water flow corrosion have focused on the determination of the transition criteria from water-wetting to oil-wetting. In many situations, the criteria need to be properly applied along with the calculations of the two phase flow mass and momentum conservation. In this paper, a unified oil/water flow model was employed to simulate the transitions from stratified types of flow to dispersed types of flow. In addition, for stratified types of flows, the curvature of the interface is determined from the minimum of the total system energy. The predicted curved interface results in different clock positions of corrosion compared to a flat interface. An example study is given to show how this flow model can be employed to grade different types of oils in terms of susceptibility to corrosion and to study the effects of terrain on the corrosion clock positions and how it can be integrated with a corrosion model for corrosion predictions.
