Show that the stream lines and the vortex lines are orthogonal if and only if v = ϕ(∇ψ) for some scalar functions ϕ and ψ. Solution We note that the stream lines and the vortex lines are orthogonal whenever v and curl v are orthogonal.

From Examplewe recall that. E A global free boundary problem—steady vortex rings of permanent form in an ideal fluid. The notion of a steady vortex ring was discussed briefly in Chapter 1. Here we establish the existence of a family of such axisymmetric vortex rings moving with constant velocity and permanent form in an ideal fluid.

Two examples are of interest in. The ring-shaped center of rotation is drawn as a line. The rotations of the vortex ring structure draw a jet of water through the center of the ring, indicated by the arrow. (b) A three-dimensional reconstruction of a chain of three connected vortex rings.

A resulting jet of fluid undulates through the center of the vortex rings building the chain. The main general results found in our study are the following. Two vortex rings can already generate chaotic streamlines (Huang et al., ). Chaotic streamlines of two linked vortex rings never extend to infinity.

Consequently, motion far away from two linked vortex rings is regular. Motion far away from two unlinked vortex rings can be by: 2. A tentative classification scheme is proposed for vortex rings which is based on extensive hot-wire measurements of velocity in the ring core and wake, and flow visualization, viz.

laminar, wavy. A toroidal vortex ring is formed when a fast moving fluid moves through a relatively still other or different fluid. For example, smoke rings blown through air, or bubble rings in water. Vortex flow is one of the fundamental types of fluid and gas motion.

These flows are the most spectacular in the form of concentrated vortices, characterized by the localization of vorticity (curl of velocity) in bounded regions of a space, beyond which the vorticity is either absent or rapidly falls down to zero.

Concentrated vortices are often observed in nature, exemplified by atmospheric. Stirring properties of vortex rings Article (PDF Available) in Physics of Fluids A Fluid Dynamics 3(5) May with 75 Reads How we measure 'reads'.

This article addresses the fascinating years history of the classical Helmholtz paper that laid the foundation of the vortex dynamics.

A long list of papers on vortex motions in general and particularly on vortex ring dynamics for the period is found in the bibliography by Akhmetov et al. Basic theoretical models of vortex rings and present-day results will be discussed with the corresponding references throughout the book.

Maxworthy (J. Fluid Mech., vol. 64,pp. –) and Glezer & Coles (J. Fluid Mech., vol.pp. –) each developed models to describe the long-term physics of turbulent. This work contains not only the general theorems on vortex motion, but also a special section devoted to axisymmetric circular vortex filaments and, in particular, to vortex rings.

Recall that streamlines are lines everywhere tangent to the velocity. dy dx = v u, so potential lines are perpendicular to the streamlines. For inviscid and irrotational flow is indeed quite pleasant to use potential function,!, to represent the velocity field, as it reduced the problem from having three unknowns (u, v, w) to only one.

Dynamics of thin vortex rings in ğ) we have M pV p = ρΓπR2, () where M p is the mass of water displayed by the piston and V p =L/T is the velocity of the piston. At the same time, when the ring is moving with its bubble at velocity V, M pV p = M bV, () where V is the velocity of the vortex ring and M b is the mass of fluid in the ring– bubble complex.
