“…Although several dynamic contact angle models have been developed to date, [64][65][66] it is still difficult to judge whether these can be applied to the situation in this study. Similar to recent numerical studies on dynamic liquid droplets and bubbles on the wall surface, [67][68][69][70] a static contact angle was employed in this study. This means that the hysteresis of the contact angle on the wall surface was not considered.…”

In this study, we investigated the detachment of an oil droplet from a wall surface by microbubbles (MBs) using the numerical simulation of a gas–liquid–liquid three‐phase flow based on a phase‐field model. A single MB was collided with an oil droplet adhered to a wall surface to determine whether the droplet would detach from the wall. It was confirmed that the oil droplet detached from the wall when the interfacial tension between the water and oil or between the bubble and oil was low. To clarify the mechanism, we theoretically calculated the balance of interfacial tension at the three‐fluid contact line. The lower the interfacial tension between the water and oil and between the bubble and oil, the smaller the contact angle of the oil droplet on the bubble. This increased wettability was the driving force that caused the oil droplet to detach from the wall surface.
