ELECTROWETTING: A simulation of a variable-focus liquid lens for a miniature camera during the transition between focal lengths. The lens is made from the interface between two fluids – the lower phase velocity field is colored, the upper phase is shown by an arrow plot. The electrowetting effect is used to change the contact angle at the edge of the cylinder, creating a different meniscus radius and so modifying the focal length of the lens.
The Microfluidics Module brings easy-to-use tools for the study microfluidic devices and rarefied gas flows. Important applications include simulations of lab-on-a-chip devices, digital microfluidics, electrokinetic and magnetokinetic devices, inkjets, and vacuum systems.
