Divergence - two phase flow

narendra.gadwal · October 7, 2014, 03:07

I am trying to simulate a two phase flow - water and water vapor.

I know the mass flow rates of two phases entering from a single inlet and pressure outlet BC.

I did not consider phase change too.

I tried simple and PISO , result is same

Need some advice

You need to provide a lot more information. What code are you using? What is the dominate phase (water droplets in steam, steam bubbles in water, or both)? What multiphase model are you using? (Eulerian/Eulerian, Eulerian/Lagrangian, slip velocity, VOF)?

Model used: Mutliphase Mixture

Dominant phase if water and it has 20% of water vapor.

Considered liquid water as primary phase.
