Multiphase flow

Multiphase flows are a branch of fluid mechanics.

In the normal fluid mechanics only one fluid (eg water) considered in multiphase flows considered one currents of different substances, such as water and oil, or, in general, several different combinations of fluids or gases, liquids and solids.

Division into

• Separate multiphase flows (eg film flow )
• Discontinuous multiphase flows (eg, plug flow ) similarly large volume fractions of the individual phases
• Disperse multiphase flows, consisting of a continuous phase with a high volume fraction of the disperse phase and in particulate form.

CFD models for disperse multiphase flows:

• Euler Euler model ( each phase will be considered as a continuum )
• Euler -Lagrange model ( single particle observation in the flow )
• Algebraic Slip Model
• Euler - Granular Model

CFD model for separated multiphase flows:

• Volume-of - fluid method
• Level set method
