Discrete Set Selection of Saffman-Taylor Fingers

Research output: Contribution to journalArticlepeer-review


A study of the linear stability of the discrete set of steady‐state Saffman–Taylor finger solutions at finite surface tension is presented. It is shown by explicit computation that members of the set aside from the lowest width finger are linearly unstable. This completes the demonstration that finite surface tension effects determine uniquely the allowed interfacial pattern in the steady‐state regime.
