Abstract
A surface tension model has been developed in the
finite volume particle method (FVPM). Surface tension force is
applied only on free-surface particles, which are inexpensively
and robustly detected using the FVPM definition of interparticle
area. We present a simple model in which the direction of the
pairwise surface tension force is approximated by the common
tangent of free-surface particle supports. The method is validated
in 2D for formation of an equilibrium viscous drop from square
and elliptical initial states, drops on hydrophobic and hydrophilic
walls, and impact of a small cylinder on a liquid surface. Results
are practically free from parasitic current associated with
inaccurate curvature determination in some methods.
