| dc.description.abstract | We present a computational analysis of the flow of liquid foam along a smooth wall, as encountered
in the transport of foams in vessels and pipes. We concentrate on the slip of the bubbles at the wall
and present some novel finite element calculations of this motion for the case of fully mobile
gas/liquid interfaces. Our two-dimensional simulations provide for the first time the bubble shapes
and entire flow field, giving detailed insight into the distribution of stresses and dissipation in the
system. In particular, we investigate the relationship between the drag force and the slip velocity of
the bubble, which for small slip velocities obeys power laws, as predicted by previous
semianalytical treatments. | en |
