Capillary fracture of ultrasoft gels: heterogeneity and delayed nucleation
Marion Grzelka, Joshua B. Bostwick, Karen E. Daniels
A droplet of surfactant spreading on an ultrasoft ( Pa) gel substrate will produce capillary fractures at the gel surface; these fractures originate at the contact-…
Dynamics of sessile drops. Part 3. Theory of forced oscillations
Joshua B. Bostwick, Paul H. Steen
A partially-wetting sessile drop is driven by a sinusoidal pressure field that produces capillary waves on the liquid/gas interface. The analysis presented in Part 1 of this series…
Wetting dynamics of a collapsing fluid hole
Joshua Bostwick, Joshua Dijksman, Michael Shearer
The collapse dynamics of an axisymmetric fluid cavity that wets the bottom of a rotating bucket bound by vertical sidewalls are studied. Lubrication theory is applied to the govern…
Elastocapillary deformations on partially-wetting substrates: rival contact-line models
Joshua B. Bostwick, Michael Shearer, Karen E. Daniels
A partially-wetting liquid can deform the underlying elastic substrate upon which it rests. This situation requires the development of theoretical models to describe the wetting fo…
Capillary fracture of soft gels
Joshua B. Bostwick, Karen E. Daniels
A liquid droplet resting on a soft gel substrate can deform that substrate to the point of material failure, whereby fractures develop on the gel surface that propagate outwards fr…
Excited Sessile Drops Dance Harmonically
Chun-Ti Chang, Susan Daniel, Paul H. Steen
In our fluid dynamics video, we demonstrate our method of visualizing and identifying various mode shapes of mechanically oscillated sessile drops. By placing metal mesh under an o…
