Greetings, I am currently attempting to simulate a 2D air-water flow in horizontal pipe with different superficial velocities, e.g. two inlets each with different liquid and gas velocity respectively. I cannot seem to get the expected outcome based on the flow pattern or pressure profile.

I attempted the separate the pipe into half whereby the top half of the domain is gas inlet whereas the bottom half is water inlet.

Below are some of the details of the simulation:

Pipe length: 3m

Pipe diameter: 0.0254m

Multiphase model: VOF

Viscous: k-epsilon

Vsg: 1 m/s

Vsl: 0.8 m/s

Pressure velocity coupling : SIMPLE

Any help would be appreciated.

please check your correction factor

for an example

momentum under relaxation factor- 0.3
pressure under relaxation factor -0.7
