Which flow regime is described by gas dispersed as droplets within the other phase?

• A. Distributive flow
• B. Segregated flow
• C. Intermittent flow
• D. Annular flow

Answer: (A)

Distributive flow describes a two-phase regime where the minority phase is broken into droplets or small bubbles that are dispersed throughout the continuous phase. In this case, gas appears as numerous small droplets scattered across the cross-section of the flow, rather than forming a separate, continuous layer or slug with the liquid. This is different from segregated flow, where the phases occupy distinct regions with a clear interface; annular flow, where one phase forms a core and the other flows as a surrounding film on the walls; and intermittent flow, where phases alternate in time and space, creating slugs or pockets. So the description of gas dispersed as droplets within the other phase fits distributive flow best, such as air bubbles dispersed in water within a pipe.
