...Zhiliang Wan; Hongjun Zeng; Alan Feinerman This paper reports experimental investigations on the electrowetting effect of liquid metals, e.g., mercury, on dielectric films. Largest contact angle change of 74 deg (from 141 deg to 67 deg ) is achieved on top of a Parylene film. Highly reversible...

Numerical simulations of the liquid metal flow around the cylindrical sand core and analysis of dynamic forces acting on the core during the fill process showed that a buoyancy...
