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.

Concepts and notations, Flow Patterns in vertical tube, and horizontal tubes.
Homogeneous and separated flow models, frictional pressure drop, Separated Flow Model, and void fraction.
Two-phase flow regimes and heat transfer predictions.
Flow regimes, and heat transfer predictions.
Two-phase flow patterns, flow condensation, flow evaporation and boiling.
