I. INTRODUCTION Using singular structures as approximations for finite-size objects is common in fluid mechanics. Point vortices represent smooth finite-size vortices, infinitely thin boundary layers replace finite-thickness ones and in multiphase flows point particles are commonly used to model finite-size drops, bubbles, and solid particles. Likewise, thin films are often modeled as one or two-dimensional lines and sheets.
