We develop a new numerical framework, employing physics-informed neural networks, to find a smooth self-similar solution for the Boussinesq equations. The solution corresponds to an asymptotic self-similar profile for the 3-dimensional Euler equations in the presence of a cylindrical boundary. In particular, the solution represents a precise description of the Luo-Hou blow-up scenario [G. Luo, T. Hou, Proc. Natl. Acad. Sci. 111(36): 12968–12973, 2014] for the 3-dimensional Euler equations.

TLDR
A local analysis near the point of the singularity suggests the existence of a self-similar blowup in the meridian plane and a class of potentially singular solutions to the Euler equations computed in axisymmetric geometries.

TLDR
This paper attempts to provide an affirmative answer to this long-standing open question from a numerical point of view, by describing a class of rotationally symmetric flows from which infinitely fast spinning vortices can form in finite time.
