Historically, probably the most commonly studied cases of two-phase flow are in large-scale power systems.

Even more critically, nuclear reactors use water to remove heat from the reactor core using two-phase flow.

Another case where two-phase flow can occur is in pump cavitation.

Several features make two-phase flow an interesting and challenging branch of fluid mechanics:

Recent work in the field has focused on the potential of two-phase flows at the micro-scale.

Since the same mathematics describes two-phase and two-component flows, the two expressions can be treated as synonymous.

The modeling of two-phase flow is still under development.

In the homogeneous model of two-phase flow, the slip ratio is by definition assumed to be unity (no slip).

(8) is very accurate in single-phase conditions but inaccurate to measure two-phase flows.

On the other hand in two-phase flows, the meter consistently gives negative errors.
