Journal ArticleDOI
Viscous and resistive eddies near a sharp corner
TL;DR: In this paper, it was shown that when either or both of the boundaries is a rigid wall and when the angle between the planes is less than a certain critical angle, any flow sufficiently near the corner must consist of a sequence of eddies of decreasing size and rapidly decreasing intensity.
Journal ArticleDOI
The degree of knottedness of tangled vortex lines
TL;DR: In this paper, the integral integral of the velocity field in a fluid of infinite extent due to a vorticity distribution w(x) which is zero except in two closed vortex filaments of strengths K1, K2 was shown.
Journal ArticleDOI
Helicity in Laminar and Turbulent Flow
H. K. Moffatt,A. Tsinober +1 more
TL;DR: In this article, the authors define a helical flow u = U+1/2f~ x where U and f are constants and u is the helicity density of the flow.
Journal ArticleDOI
Helicity and the Calugareanu Invariant
H. K. Moffatt,Renzo L. Ricca +1 more
TL;DR: In this paper, a topological interpretation of helicity in terms of the Gauss linking number and its limiting form (the Calugareanu invariant) is presented, and a new and direct derivation of this topological invariant from the invariance of helicity is given.
