| Zusammenfassung |
| The paper concerns the temporal evolution of the Rayleigh-Taylor instability of two superimposed fluids in a
vertical channel. At large times the instability results in the formation of a wide
nearly-steady bubble of the lighter fluid rising through the channel, and thin long
unsteady jets of the heavier fluid flowing down the channel walls. The jet flow appears to
be tractable asymptotically by the method of matched expansions. The solution has been
obtained with the planar tips of jets characterized by the jump of the interface slope. |
