...Sucharitha Rajendran; Raj M. Manglik; Milind A. Jog To predict liquid–gas two-phase flow, accurate tracking of the evolving liquid–gas interface is required. Volume-of-fluid (VoF) method has been used for computationally modeling such flows where a single set of governing equations are solved...

... quantified. For both the single and two-phase flows, it has been observed that the pressure drop decreases with area ratio, and increases with mass flux and mass flow quality of two-phase flow. The vena contracta for a single-phase flow was found. But for two-phase flow, neither the vena contracta nor...

These ranges cover single-phase and the bubbly, slug and churn two-phase flow regimes. It was found that for the single-phase flow experiments, the valve...

... is mainly reflected in that the microvascular blood is considered as a two-phase fluid composed of a continuous phase (plasma) and a discrete phase (red blood cells (RBCs)). And plasma flow state is quantitatively described based on the Navier–Stokes equation of two-phase flow theory, the effect of momentum...
