Abstract
Solutions are reported for the problem of the motion of a two-dimensional interface between a viscous and a nonviscous fluid. The solution has the interface moving uniformly while the viscous fluid has a nontrivial potential flow. In an alternative interpretation, there are gravitational forces in the plane which allow the interface to be at rest while the fluid is in motion.Keywords
