Resumo(s)
We examine steady flows of a thin film of viscous fluid on the inside of a cylinder
with horizontal axis, rotating about this axis. If the amount of fluid in the cylinder
is sufficiently small, all of it is entrained by rotation and the film is distributed
more or less evenly. For medium amounts, the fluid accumulates on the ‘rising’
side of the cylinder and, for large ones, pools at the cylinder’s bottom. The paper
examines rimming flows with a pool affected by weak surface tension. Using the
lubrication approximation and the method of matched asymptotics, we find a
solution describing the pool, the ‘outer’ region, and two transitional regions, one of
which includes a variable (depending on the small parameter) number of asymptotic
zones.
