Breakup of a supported drop of a viscous conducting liquid in a uniform electric field.
Numerical computations and order-of-magnitude estimates are used to describe the time evolution of a drop of a very viscous liquid of finite electrical conductivity attached to a metallic plate which is suddenly subject to a uniform electric field. Under the action of the electric stresses induced at its surface, the drop elongates in the direction of the field, and charged droplets are emitted...
متن کاملViscous to inertial crossover in liquid drop coalescence.
Using an electrical method and high-speed imaging, we probe drop coalescence down to 10 ns after the drops touch. By varying the liquid viscosity over two decades, we conclude that, at a sufficiently low approach velocity where deformation is not present, the drops coalesce with an unexpectedly late crossover time between a regime dominated by viscous and one dominated by inertial effects. We a...
متن کاملNumerical Simulation of Deformation / Motion of a Drop Suspended In Viscous Liquids Under Influence of Steady Electric Fields
The deformation / motion of a droplet suspended in a viscous liquid under the influence of an applied external electrical field are investigated through numerical simulations. The two-phase flow field of the drop suspension system is simulated using a front tracking / finite volume method for solving the full Navier-Stokes equations. Three different electric field models are applied in order to...
متن کاملNeutral donor-acceptor-pair recombination under a uniform electric field.
The kinetics of the recombination of electrons trapped by donors, with holes trapped by acceptors, in semiconductor materials within a uniform electric field has been investigated. A simple form has been derived which shows that the decay rate of neutral donor-acceptor-pair {DAP) recombination increases under the presence of the electric field. This analysis can also be applied to the processes...
متن کامل3d Numerical Simulation of Drop Coalescence∗
The major importance of drop coalescence in a number of natural and industrial processes provides the motivation for fundamental experimental and theoretical studies on its mechanics. One of the main difficulties of such investigations is related with the presence of a thin liquid film, typically of order 10−4 of the drop size. In numerical studies of coalescence this requires very fine spatial...
