Slug Flow in channel

Dear All
I am trying to model the Slug Flow in rectangular channel by 2D simulation. The dimentions are length=8000mm and height=100mm. The grid consists of 100000 quadrilateral elements. There is some problem in convergence of continuity equation. Major properties of model are: -2d,vof,Standard k-omega,pressure based -distinct velocity inlet for air and water,pressure outlet for outlet -equ:flow,volume fraction,turbulence -pressure velocity coupling=PISO -descretization Schemeressure-presto,momentum=quick and for other equations=second order both of phase are incomperssible. Lower 50% of channel is filled by water and upper 50% section is full of water. The enterance velocity of water=2m/s and enterance velocity of air=10m/s. I know the main reason of problem is intial condition. but unfortunately,I cant find the appropriate IC for this turbulence model. Any suggestions will be appreciated. Thanks in advance |

Have you tried with k-epsilon?? to knlow if the problem is the turbulence model.

Hi figd84
thanks for your suggestion but I tried k-e befor and I have same problem again. |
