Emulsification of water and fuel oil emulsion was experimentally investigated. The water-in-oil emulsion was produced with ultrasonic mixer and phase inversion concentration using a mixture of Span80 and Tween80 as emulsifiers. The emulsion was characterized by water droplet size, distribution and visual observation of microscopy photographs. Water in fuel oil emulsion prepared by phase inversion concentration was found to be similar to that prepared by the ultrasonic mixer in term of average droplet size and distribution

The recent development of a superhydrophobic surface enhances the droplet shedding under a shear flow. The present study gives insights into the effects of shear flow on a pinned droplet over a superhydrophobic surface. To experimentally simulate the change in the size of a sessile droplet on an aerodynamic surface, the volume of the pinned droplet is expanded by water supplied through a pore. Under a continuous airflow that provides a shear flow over the superhydrophobic surface, the size of a pinned water droplet shed from the surface is experimentally characterized. The air velocity ranges from 8 to 61 m/s, and the size of pinned droplets shed at a given air velocity is measured using an instantaneous snapshot captured with a high-speed camera. It is found that the size of the shedding pinned droplet decreases as air velocity increases. At higher air velocities, shedding pinned droplets are fully immersed in the boundary layer. The present findings give a correlation between critical air velocity and the size of pinned droplets shed from the pore over the superhydrophobic surface.
