Emulsification, separation, and manipulation of oil-water systems using condensation, electrocoalescence, and electrowetting
… separate oil and water using low-voltage electrocoalescence, and manipulate oil and water using ultra low-voltage electrowetting. The emulsification method relies on condensation of one liquid phase onto another. As nanoscale droplets of water condense onto the surface of oil, they are …

Droplets in an Electric Field: Surface Rheology, Coalescence and Rebound
<p>Electrocoalescence is the process in which pairs of conducting droplets suspended in a continuous dielectric (nonconducting) liquid phase are drawn together and merge upon the application of an electric field. The electric field polarizes each of the droplets in the field direction. The …

O processo de eletrocoalescência na separação de água e óleo em emulsões modelo e de petróleo
The electrocoalescence process is widely used in the petroleum industry for separation of water in oil emulsions. However, the understanding of process mechanisms is not yet complete due to the high complexity of the system, which involves electrostatic and dynamic interactions. Thus, this …

Hydrodynamic and Mass Transport Properties of Microfluidic Geometries
<p>Microfluidic geometries allow direct observation of microscale phenomena while conserving liquid volumes. They also enable modeling of experimental data using simplified transport equations and static force balances. This is possible because the length scales of these geometries ensure low Re …
