Abstract:
This paper presents the shape deformation of a single two dimensional spherical liquid droplet on a horizontal surface. The mathematical model can be defined by the time-dependent Navier-Stokes equations in a time-dependent domain. The model has to be completed by the free boundary condition on the fluid-gas interface and the Navier-slip boundary condition on the fluid-solid interface, respectively. A second order finite element discretization in space is combined with a fractional theta-scheme to solve this free surface problem. The Arbitrary Lagrangian Eulerian method is used to handle the time dependent domain. Replacing the curvature term on the free surface by the Laplace-Beltrami operator we are able to include the contact angle explicitly in the finite element formulation. The numerical results show that the shape deformation is influenced by the impact velocity, the droplet diameter, the surface tension and material properties.

Title:
Effects of Surface Wettability on Bubbles in Nanochannels
Authors:
Xie, H; Liu, C
Author Full Names:

ACTA PHYSICO-CHIMICA SINICA 25 (12): 2537-2542 DEC 2009

Abstract:
Molecular dynamics simulations were carried out to study the distribution and movement of bubbles in nanochannels with different wettabilities when the fluids were driven by mass force. A method for calculating the velocity of a bubble in a nanochannel was presented. Results reveal that bubbles are present in the middle of nanochannels with hydrophilic surfaces and their velocities are close to but lower than the flow velocity in the middle of the nanochannel. At higher potential energies, the bubbles are larger because the surface absorbs more particles. Otherwise, the bubbles would be smaller. Two bubbles are symmetrical on both surfaces of the nanochannel when their surfaces are superhydrophobic and their velocities are close to but larger than the flow velocity at the edge of the nanochannel. The fluid flow speeds up as the interaction decreases between fluid molecules and wall particles while the slip velocity gradually changes from negative to positive.
