[COMSOL] Why two phase (oil-oil) laminar multiflow in microfluidics simulation causing bubble formation and not smooth flow like real experiment?

I am trying to simulate my experiment conducted in microchannel with two newtonian and non-newtonian paraffin oil based fluids using comsol. While in the actual experiment, the two fluids flow in...
