Pattern of inclusions inside rippled icicles
John Ladan, Stephen W. Morris
Icicles that have grown from slightly impure water develop ripples around their circumference. The ripples have a near-universal wavelength and are thought to be the result of a mo…
On the origin and evolution of icicle ripples
Antony Szu-Han Chen, Stephen W. Morris
Natural icicles often exhibit ripples about their circumference which are due to a morphological instability. We present an experimental study that explores the origin of the insta…
Frequency structure of the nonlinear instability of a dragged viscous thread
Robert L. Welch, Billy Szeto, Stephen W. Morris
A thread of viscous fluid falling onto a moving surface exhibits a spectacular variety of types of motion as the surface speed and nozzle height are varied. For modest nozzle heigh…
Experiments on the morphology of icicles
Antony Szu-Han Chen, Stephen W. Morris
Icicles form when cool water drips from an overhanging support under ambient conditions which are below freezing. Ice growth is controlled by the removal of latent heat, which is t…
Scaling and dynamics of washboard road
Anne-Florence Bitbol, Nicolas Taberlet, Stephen W. Morris +1
Granular surfaces subjected to forces due to rolling wheels develop ripples above a critical speed. The resulting pattern, known as "washboard" or "corrugated" road, is common on d…
Washboard Road: The dynamics of granular ripples formed by rolling wheels
Nicolas Taberlet, Stephen W. Morris, Jim N. McElwaine
Granular surfaces tend to develop lateral ripples under the action of surface forces exerted by rolling wheels, an effect known as washboard or corrugated road. We report the resul…
