Two-phase flow is a flow involving two different fluids flowing simultaneously in a channel. The characteristics of two-phase flow are more complex than single-phase flow because they are influenced by phase interaction, phase distribution, superficial velocity, and friction occurring during the flow process. These interactions cause pressure distribution changes along the pipe and require furt…
