Variational formulation for the dynamics of soft matter including inertia

The motion of liquids and soft matter is over-damped and “slow” when viscosity dominates. In this (low Reynolds-number) limit and when the system is isothermal, the equations of motion may be generated via Onsager’s variational principle, which neglects inertia. This variational...

Liquid bridges between horizontal cylinders: Effects of gravity and electric fields

Liquid bridges suspended between two parallel horizontal cylinders are studied using experiments, reduced-order mathematical modelling and numerical simulations. Both non-electrified and electrified configurations are considered, with the cylinders acting as electrodes between wh...
