Regularity of 3D axisymmetric Navier-Stokes equations

Abstract

In this paper, we study the three-dimensional axisymmetric Navier-Stokes system with nonzero swirl. By establishing a new key inequality for the pair $(\frac{{\omega }^r}{r},\frac{{\omega }^{\theta }}{r})$, we get several Prodi-Serrin type regularity criteria based on the angular velocity, $u^{\theta }$. Moreover, we obtain the global well-posedness result if the initial angular velocity $u_0^{\theta }$ is appropriate small in the critical space $L^3({\mathbb{R}}^3)$. Furthermore, we also get several Prodi-Serrin type regularity criteria based on one component of the solutions, say ${\omega }^3$ or $u^3$.
