MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Capillary Forces on Partially Immersed Plates

Robert Finn

Abstract

This is a partly historical outline of material related to the general question of mutual attraction and repulsion of bodies floating on an unbounded fluid surface in the presence of a gravity field and subject to surface tension interactions with the free surface interface. Discussion centers on a simplified model originally introduced by Laplace, and later re-introduced in more detailed studies, initially by the author and then by the author with Devin Lu, concerning the horizontal forces that can arise when two parallel plates of perhaps differing materials are dipped vertically into an unbounded fluid bath, in the presence of a gravity field. Despite the conceptual simplifications intrinsic to the model, a remarkable variety of behavior can occur, encompassing a singular perturbation that leads to strikingly discontinuous limiting behavior as the plates approach each other.
