We discuss necessary and sufficient conditions for the formation of finite time singularities (blow up) in the incompressible three dimensional Euler equations. The well-known result of Beale, Kato and Majda states that these equations have smooth solutions on the time interval (0,t) if, and only if lim/t{r_arrow}T {integral}{sup t}{sub 0} {parallel}{Omega}({center_dot},s){parallel}{sub L}{sup {infinity}} (dx)dx < {infinity} where {Omega} = {triangledown} X u is the vorticity of the fluid and u…

Vortex Stretching by a Simple Hyperbolic Saddle

We study solutions to the 3D Euler vorticity equation of the form \(\omega = \tilde \omega (x,t)\left( {\frac{{\partial t}}{{\partial {x_2}}},\frac{{\partial t}}{{\partial {x_1}}},0} \right) \) in a…

The 3D Incompressible Euler Equations with a Passive Scalar: A Road to Blow-Up?

It is shown that smooth solutions blow up in a finite time if a null (zero) point develops in the vector B=∇q×∇θ, provided B has no null points initially.

An Example of Finite-time Singularities in the 3d Euler Equations

Abstract.Let $$\Omega = {\user2{\mathbb{R}}}^{3} \backslash \overline{B} _{1} (0)$$ be the exterior of the closed unit ball. Consider the self-similar Euler system $$\alpha u + \beta y \cdot…

Some advances on the geometric non blow-up criteria of incompressible flows

One of the most challenging questions in fluid dynamics is whether the three-dimensional (3D) incompressible Navier-Stokes, Euler and two-dimensional Quasi-Geostrophic (2D QG) equations can develop a…

A sufficient condition is derived for a finite-time $L_2 $ singularity of the 3d incompressible Euler equations, making appropriate assumptions on eigenvalues of the Hessian of pressure. Under this…

Finite Time Blowup for Lagrangian Modifications of the Three-Dimensional Euler Equation

In the language of differential geometry, the incompressible inviscid Euler equations can be written in vorticity-vector potential form as $$\begin{aligned} \partial _t \omega + {\mathcal {L}}_u…

A Lower Bound on Blowup Rates for the 3D Incompressible Euler Equation and a Single Exponential Beale-Kato-Majda Type Estimate

We prove a Beale-Kato-Majda type criterion for the loss of regularity for solutions of the incompressible Euler equations in $${H^{s}(\mathbb {R}^3)}$$ , for $${s>\frac{5}{2}}$$ . Instead of double…

Reconnection and the road to turbulence (Coherent Vortical Structures : Their Roles in Turbulence Dynamics)

It will be noted that several initial conditions besides anti-parallel vortices give varying degrees of evidence for a singularity of the incompressible Euler equations. The primary test is whether…
