Desingularization of periodic vortex sheet roll-up
TL;DR: In this article, an analytical approach is used in an attempt to model the evolution of a vortex sheet past the critical time by means of a desingularization method, which converges beyond critical time for the vortex sheet.

The method of regularized Stokeslets in three dimensions : Analysis, validation, and application to helical swimming
TL;DR: The regularized Stokeslet method as discussed by the authors is a Lagrangian method for computing Stokes flow driven by forces distributed at material points in a fluid, which is based on the superposition of exact solutions of the Stokes equations when forces are given by a cutoff function.
