ABSTRACT

----------------------------------------

The spreading of a viscous liquid drop on a solid surface is a problem of both fundamental concern and practical interest.  From the mathematical point of view, the challenge is to remove a singularity -- an infinite force at the moving contact line, which is a physically unrealistic feature.  In order to remove it, is has been proposed that the no-slip condition be relaxed or the contact angle be 180 degrees.  Here I will use the boundary-element method to show the spreading of a viscous drop over a rigid, horizontal, no-slip surface.
