Abstract  

The behavior of nano-fluids, or fluid suspensions containing nanoparticles in the realm of capillary fluid flow, has garnered tremendous attention recently for applications spanning from household and personal care products to advanced targeted drug therapy and materials fabrication. One concern is how to control the ordering of nano-particle arrays and fabricate those functional devices. Nano-suspension provides us with a path to synthesize and disperse nanoparticles in fluids, however, the fundamental mechanisms about interfaces and wetting kinetics are still unknown when a nanosuspension drop spreads on a solid surface. Herein, results from molecular dynamics simulations will be presented to explore the nanosuspension metal droplet impact process. Furthermore, the results illustrate how the role of impact angle, impact velocity and nanoparticle size affect the spreading kinetics and how this connects dynamic droplet morphology and associated particle positioning on surfaces.
