Surface tension effects in a wedge
( Mathematics Department, University of Western Australia, Nedlands, Western Australia 6009, Australia )
The linearized Laplace-Young capillary equation has been solved for the depth of liquid contained in a region bounded by vertical walls at an arbitrary wedge angle 2
using the Kantorovich-Lebedev transform. These solutions accurately describe the surface displacement for surface contact angles
close enough to
/2, for both convex and concave (re-entrant) wedge angles.
By matching solutions of the linearized Laplace-Young equation solutions on the exactly known one-dimensional nonlinear Laplace-Young wall solutions, far-field approximations are obtained for arbitrary contact angle
situations for possibly a restricted range of wedge angles.
