Numerical modeling of the equilibrium shapes of a ferrofluid drop in an external magnetic field
The main objective of the work is to develop a numerical solution strategy for calculating equilibrium shapes of a ferrofluid drop subjected to a uniform applied magnetic field. The free boundary value problem is governed by a coupled system of Maxwell’s equations for the magnetic field distribution and Young-Laplace equation for the free surface shape. Maxwell’s equations are formulated in the...
متن کاملEquilibrium shapes of a twist-bend nematic drop
These notes supplement our paper Interfacial and morphological features of a twist-bend nematic drop, producing a number of analytical details of the mathematical model employed there to interpret the experimental observations of equilibrium shapes of a twist-bend nematic drop in two space dimensions. For the sake of continuity and completeness, some figures and equations are also reproduced here.
متن کاملEquilibrium structure of ferrofluid aggregates.
We study the equilibrium structure of large but finite aggregates of magnetic dipoles, representing a colloidal suspension of magnetite particles in a ferrofluid. With increasing system size, the structural motif evolves from chains and rings to multi-chain and multi-ring assemblies. Very large systems form single- and multi-wall coils, tubes and scrolls. These structural changes result from a ...
متن کاملDynamics of ferrofluid drop deformations under spatially uniform magnetic fields
We systematically study the shape and dynamics of a Newtonian ferrofluid drop immersed in an immiscible, Newtonian and non-magnetic viscous fluid under the action of a uniform external magnetic field. We obtain the exact equilibrium drop shapes for arbitrary ferrofluids, characterize the extent of deviations of the exact shape from the commonly assumed ellipsoidal shape, and analyse the smoothn...
متن کاملEquilibrium shapes of flat knots.
We study the equilibrium shapes of prime and composite knots confined to two dimensions. Using scaling arguments we show that, due to self-avoiding effects, the topological details of prime knots are localized on a small portion of the larger ring polymer. Within this region, the original knot configuration can assume a hierarchy of contracted shapes, the dominating one given by just one small ...
