Question

Which is better in between 2 phase n multiphase flow?

Answer 1

$\huge\underline\orange{\sf Answer}$

Single-phase vs Multi-phase Fluid Flow. This is a basic classification. Solution of multi-phase fluid flow is very complex and difficult and it is in advanced courses of fluid dynamics.

Answer 2

Explanation:

Two-phase flow can occur in various forms, such as flows transitioning from pure liquid to vapor as a result of external heating, separated flows, and dispersed two-phase flows where one phase is present in the form of particles, droplets, or bubbles in a continuous carrier phase (i.e. gas or liquid).
