Clustering Analysis of Periodic Point Vortices with the L Function
نویسنده
چکیده
A motion of point vortices with periodic boundary conditions is studied by using Weierstrass zeta functions. Scattering and recoupling of a vortex pair by a third vortex becomes remarkable when the vortex density is large. Clustering of vortices with various initial conditions is quantitated by the L function used in point process theory in spatial ecology. It is shown that clustering persists if it is initially clustered like an infinite row or a checkered pattern.

Point Process Analysis of Vortices in a Periodic Box
The motion of assemblies of point vortices in a periodic parallelogram can be described by the complex position zj(t) whose time derivative is given by the sum of the complex velocities induced by other vortices and the solid rotation centered at zj . A numerical simulation up to 100 vortices in a square periodic box is performed with various initial conditions, including single and double rows...
متن کاملPoint Vortices in a Periodic Box Makoto Umeki
A statistical approach to a problem of assemblies of point vortices (PVs) goes back to Onsager (1949). A state of negative temperature is considered to be related to clustering of vortices rotating in the same direction and the inverse energy cascade predicted in the two-dimensional Navier-Stokes (2D NS) turbulence. In many numerical simulations, PVs are bounded in a circular wall, since a velo...
متن کاملVibration of Road Vehicles with Non linear Suspensions
In order to investigate the effects of non-linear springs in vibrating behavior of vehicles, the independent suspension of conventional vehicles could be modeled as a non-linear single degree of freedom system. The equation of motion for the system would be a non-linear third order ordinary differential equation, when considering the elasticity of rubber bushings in joints of shock absorber. It...

The purpose of this paper is to study the higher order asymptotic distributions of the eigenvalues associated with a class of Sturm-Liouville problem with equation of the form w??=(?2f(x)?R(x)) (1), on [a,b, where ? is a real parameter and f(x) is a real valued function in C2(a,b which has a single zero (so called turning point) at point 0x=x and R(x) is a continuously differentiable function. ...

Topological techniques are used to study the motions of systems of point vortices in the infinite plane, in singly-periodic arrays, and in doubly-periodic lattices. The reduction of each system using its symmetries is described in detail. Restricting to three vortices with zero net circulation, each reduced system is described by a one degree of freedom Hamiltonian. The phase portrait of this r...
