Asymptotic behavior of global vortex rings

Analysis of PDEs 2019-10-17 v1

Abstract

In this paper, we are concerned with nonlinear desingularization of steady vortex rings in R3\mathbb{R}^3 with given general nonlinearity ff. Using the improved vorticity method, we construct a family of steady vortex rings which constitute a desingularization of the classical circular vortex filament in the whole space. The requirements on ff are very general, and ff may have a simple discontinuity at the origin. Some qualitative and asymptotic properties are also established.
