Default Modelling a bubble flow ina microchannel

Hi guys,

I am trying to model a bubble in a channel. I am trying to solve it in a 2D axisymmetric way. I have problems in meshing. What kind of mesh should i use? Sliding mesh or Dynamic mesh. I am using a constant velocity at the inlet will the wall being stationary. Do i need to change it with a moving wall boundary condition? I want the bubble to move with the flow. I have done something that has got a static bubble in it. The bubble for the time being is of the same density of the fluid so as to neglect the buoyancy effects. Please help.
