Binormal flow
The vortex filaments are present in 3-D fluids having vorticity concentrated along a curve, and are a key element of quantum and classical fluid turbulent dynamics. This low regularity framework is difficult to analyze through the Euler and Navier–Stokes equation; it is however at the heart of current investigations (see … See more A classical problem of mathematical analysis is finding real variable functions that are continuous but not differentiable at any point.

Webvector field on is the binormal vector field of, and the sign of the z-dimension of is positive if B is upward and is negative if it is downward. Therefore, we consider the sign of the binormal vector. In 2D the sign of the binormal vector can be obtained using the cross product of the two vectors and as follows: B T u N < < B B (vi) T (vi) N (vi) WebThe binormal flow is a model for the dynamics of a vortex filament in a 3-D inviscid incompressible fluid. The flow is also related with the classical continuous Heisenberg model in ferromagnetism, and the 1-D cubic Schrödinger equation.
