Morphology of ice structures induced by a freezing rivulet
Hélie de Miramon, Wladimir Sarlin, Christophe Josserand +2
We investigate the solidification of a water rivulet flowing over a cold inclined substrate and the resulting formation of three-dimensional ice structures. Using a controlled hydr…
The macroscopic contact angle of water on ice
W. Sarlin, D. V. Papa, R. Grivet +4
Wettability quantifies the affinity of a liquid over a substrate, and determines whether the surface is repellent or not. When both the liquid and the solid phases are made of the…
Free surface topography of capillary flows using spatiotemporal phase shifting profilometry
Hélie de Miramon, Wladimir Sarlin, Axel Huerre +3
We present a novel experimental technique to characterize the free surface of capillary flows adapted from the Spatio-Temporal Phase Shifting Profilometry (ST-PSP) method introduce…
Deformation of hydrogel during freezing
Lila Séguy, Axel Huerre, Suzie Protière
We conducted experiments to directionally freeze agar hydrogel drops with different polymer concentrations, on a copper substrate maintained at low temperature. Unlike the water dr…
