Simulation of laminar flow of 2 liquids inside microchannel
 

HI guys,

i am working on simulating flow inside microchannel. actually i have 2 liquids ( with nearly same density) entering from different inlet and flowing in a single channel and coming out of 2 separate outlet at the end. I tried simulating this using multiphase flow but could not see the separating layer between the 2 liquids in the simulation. but i could c the separating layer between the 2 fluids in experiments. can any one help how to do the simulation of such cases??

thanks in advance !!!!!

Cheers
