We studied the condensation of water drops on a micro-structured lubricant-infused surfaces. Hierarchical micro-prism surfaces were fabricated by soft imprinting with wet TiO2 nanoparticle paste. After hydrophobization, the patterned surfaces were infused with silicone oil as a lubricant. When cooling at high humidity (over 80%), water drops nucleate and start growing on the surface. Once they ...

This paper introduces depth estimation from water drops. The key idea is that a single water drop adhered to window glass is totally transparent and convex, and thus optically acts like a fisheye lens. If we have more than one water drop in a single image, then through each of them we can see the environment with different view points, similar to stereo. To realize this idea, we need to rectify...

In this paper we present a method for simulating physical behaviour and rendering of water drops in real-time. Our algorithm is based on processing water information stored into a texture resembling a height map. Thus calculation on the Graphics Processing Unit is possible. Texels on the height map retrieve how much of their current water amount remains and how much water is provided from texel...

This study is about the non-uniform electric field for splitting of water in oil emulsion. If the process occurs in an inhomogeneous electrical field, the drops are polarized and then their mobility is increased. The emulsion drops will be charged and move toward the central point of splitter where the maximum intensity of electrical field has been concentrated. In this process, the drops encou...

The steady deformation and breakup of emulsion drops in a uniform electric field are considered experimentally. Due to the low volume fraction of inner drops, the emulsions can be effectively assumed as Newtonian fluids with spatial nonuniformity. The measurements of the electrical properties show that the oil-in-water (o/w) emulsion drop behaves like a conducting drop. On the other hand, the w...
