Anisotropic drop morphologies on corrugated surfaces
H. Kusumaatmaja, R. J. Vrancken, C. W. M. Bastiaansen +1
The spreading of liquid drops on surfaces corrugated with micron-scale parallel grooves is studied both experimentally and numerically. Because of the surface patterning, the typic…
The collapse transition on superhydrophobic surfaces
H. Kusumaatmaja, M. L. Blow, A. Dupuis +1
We investigate the transition between the Cassie-Baxter and Wenzel states of a slowly evaporating, micron-scale drop on a superhydrophobic surface. In two dimensions analytical res…
Modelling droplets on superhydrophobic surfaces: equilibrium states and transitions
A. Dupuis, J. M. Yeomans
We present a lattice Boltzmann solution of the equations of motion describing the spreading of droplets on topologically patterned substrates. We apply it to model superhydrophobic…
