## Free Surface Flow

There are examples in which two continuous phases are separated by an intermittent surface. Oil-water separators Free surface flows Decomposing small droplets that are highly dependent on mesh scales. There may or may not be a slip between the phases.…

## Equilibrium Multiphase Models

In some cases, there is no interest in knowing the details of the flow behavior of the two phases, but we are interested in using the exact properties for a mixture of two phases. For example, one can mention the…

## Model MUSIG (Multiple Size Group)

In the standard solution of the Eulerian-Eulerian, a dispersed phase is determined only by diameter. In some cases, the dispersed phase diameter (fluid droplets or bubbles) may be altered by fluid forces due to breaking or composition. The function of…

## Multiphase flow modeling methods

In modeling methods, several methods for modeling multiphase flows can be used. The suitability of the method depends on the nature of the multiphase flow and the physical properties involved.   Simplified multi-component methods: In these approaches for modeling the…

## Mixing and breaking of particles

The shape of liquid droplets and bubbles can change due to fluid forces and collisions. This deformation can be broken down into smaller particles by combining it into larger particles. For example, the following can be noted:   Decomposition of…
