Numerical study of the material transport in the viscous vortex dipole flow

Physics of Fluids, 2019
This paper presents a numerical study of the material transport of Lamb dipole(s) in the two-dimensional viscous flow. We focus on the properties of the rate of strain tensor, which has received less attention in the literature. It is noted that the eigenpairs of the tensor explicitly indicate the strength and direction of material stretching and ...

THEORETICAL AND EXPERIMENTAL INVESTIGATIONS OF THREE-DIMENSIONAL VISCOUS VORTEX FLOWS

1963
Abstract : The research efforts carried out at ARAP during the past five years in the field of viscous vortex motions are summarized. The work cited constitutes a rather extensive program of theoretical and experimental studies of vortex motions in general and of three-dimensional laminar and turbulent incompressible driven vortices in particular.

Simulation of controlled bluff body flow with a viscous vortex method

1998
Bluff body flows controlled in various manners are simulated with a high-resolution, gridless vortex method. Two-dimensional, unsteady, viscous simulations are utilized to illuminate the physical phenomenon underpinning certain flows of this class. Flows past a rotationally oscillating circular cylinder and flows past an elastically mounted circular ...
