Simulation of nanodroplet impact on a solid surface
A novel computational fluid dynamics and molecular kinetic theory (CFD-MK) method was developed to simulate the impingement of a nanodroplet onto a solid surface. A numerical solution of the Navier–Stokes equation using a volume-of-fluid (VOF) technique was used to model nanodroplet deformation. Dynamic contact angle during droplet impact was obtained by molecular kinetic theory. This dynamic c...

متن کاملLift-off instability during the impact of a drop on a solid surface.
We directly measure the rapid spreading dynamics succeeding the impact of a droplet of fluid on a solid, dry surface. Upon impact, the air separating the liquid from the solid surface fails to drain and wetting is delayed as the liquid rapidly spreads outwards over a nanometer thin film of air. We show that the approach of the spreading liquid front toward the surface is unstable and the spread...

متن کاملGas influence in drop impact on dry solid substrates
A numerical study by the code GERRIS of drop impact onto a solid surface is presented. It is shown that under the incompressible assumption, drop impact can still perform different behaviors by changing the density or viscosity of surrounding gas, the splash can be suppressed for small gas density or viscosity and a no-vertical frontier exists between splash and non-splash. It is suggested that...
