TLDR
In this paper, the authors calculate the flow induced by a vortex pair in a viscous fluid, which is otherwise at rest, in the presence of a plane boundary, which may be either a no-slip or a stress-free boundary.Abstract:
We calculate the flow induced by a vortex pair in a viscous fluid, which is otherwise at rest, in the presence of a plane boundary. This may be either a no-slip or a stress-free boundary. The phenomenon of rebound of the vortices from the boundary occurs for either type of boundary, and an explanation for this is offered in terms of viscous effects.read more

The impact of a vortex ring on a wall
TL;DR: In this article, the flow induced by a vortex ring approaching a plane wall on a trajectory normal to the wall is investigated for an incompressible fluid, which is otherwise stagnant.
Journal ArticleDOI
Vortex dipole rebound from a wall
TL;DR: In this paper, a numerical simulation of the first dipole rebound from the wall agrees with experimental visualizations, and each rebound is associated with the detachment of a secondary vorticity layer from a wall, these layers merge, and at a value of Reynolds number Re=1600, form a new dipole.

Dynamics and Instabilities of Vortex Pairs
TL;DR: In this paper, the characteristics and behavior of counter-rotating and corotating vortex pairs, which are seemingly simple flow configurations yet immensely rich in phenomena, have been reviewed.

Heat Transfer Enhancement by Delta-Wing-Generated Tip Vortices in Flat-Plate and Developing Channel Flows
M. C. Gentry,Anthony M. Jacobi +1 more
TL;DR: In this article, the authors used delta wings placed at the leading edge of a flat plate to generate streamwise vortices that modify the flow; the same wings were also used to modify a developing channel flow.

Vorticity Dynamics on Boundaries
TL;DR: In this article, a unified general theory of the vorticity dynamics on various boundaries for viscous compressible flows and then reviews its applications to specific problems mainly confined to incompressible flows is presented.

Boundary conditions for the numerical solution of elliptic equations in exterior regions
TL;DR: In this paper, a sequence of boundary conditions is developed which provides increasingly accurate approximations to the problem in the infinite domain and estimates of the error due to the finite boundary are obtained for several cases.

A Note on the Numerical Solution of Fourth Order Differential Equations
TL;DR: In this paper, an old numerical method of solving fourth order differential equations is put in relaxation form and the higher order correction terms are included and the technique is illustrated by an example.

The motion of two-dimensional vortex pairs in a ground effect
Steven J. Barker,Steven C. Crow +1 more
TL;DR: In this paper, a two-dimensional line vortices are generated in a water tank of dimensions 15 × 122 × 244 cm and their axes span the 15 cm width of the tank, and the flow is visualized using fluorescein dye.

The Boundary Layer Due to Rectilinear Vortex
TL;DR: The boundary layer created by the motion of a single rectilinear vortex filament above an infinite plane wall is considered in this paper, where it is conjectured that an eventual eruption of the boundary layer flow is to be expected along with a major modification of the inviscid flow.
