Abstract
In the lower portion of a horizontal rotating cylinder, the front created by dragging a viscous fluid can display the subcritical nucleation of traveling pulses. The pulse is a robust state of well defined shape and velocity. The number of pulses traveling along the front increases with angular velocity; when the angular velocity is small the front presents a chaotic behavior of colliding pulses. At a critical value the front displays a stationary periodic pattern of regular cells. This periodic state consists of a collection of interacting pulses, resulting from a new form of pattern formation.
