Dynamic labyrinthine pattern in an active liquid film.
We report the generation of a dynamic labyrinthine pattern in an active alcohol film. A dynamic labyrinthine pattern is formed along the contact line of air/pentanol/aqueous three phases. The contact line shows a clear time-dependent change with regard to both perimeter and area of a domain. An autocorrelation analysis of time development of the dynamics of the perimeter and area revealed a str...
متن کاملLabyrinthine instability in polar free-standing liquid crystalline films
We report the first study of fingering and labyrinthine instabilities in freely suspended polar liquid-crystalline films. This phenomenon is in a way the electric analogy to the labyrinthine instability in thin films of magnetic fluids. Because of the existence of a permanent polarization in the smectic films, an external electric field is not required for the spontaneous formation of the insta...
متن کاملDynamics of labyrinthine pattern formation in magnetic fluids.
A viscous ferroliquid is trapped between two narrowly spaced parallel sheets of glass, the Hele-Shaw cell. The ferroliquid lls a cylindrical domain with cross section and the rest of the cell is lled with a uid of negligible viscosity. In absence of any other forces, the eeect of surface tension at the interface between the uids is such that the liquid is at rest if is circular. Starting from t...
متن کاملLabyrinthine Turing pattern formation in the cerebral cortex.
I propose that the labyrinthine patterns of the cortices of mammalian brains may be formed by a Turing instability of interacting axonal guidance species acting together with the mechanical strain imposed by the interconnecting axons.
متن کاملLiquid Film Dynamic on the Spray Impingement Modelling
The present paper addresses a liquid film sub-model included into a computational model that aims at reproducing the spray impingement phenomena. This numerical extension incorporates the spread of the liquid film over the neighbouring nodes due to the dynamic motion induced by the film inertia but also the exchange of mass between the liquid layer and the incident and splashing particles. More...
