Two-phase flow refers to the interactive flow of two distinct phases – each phase representing a mass or volume of matter – with common interfaces in a channel. While combination between any two phases represents a significant area of two-phase flow, liquid-vapor (gas) flow is by far the most common in various industries and thus has been investigated in greater depth.
