Computational Experiments on the Tracking of Vortices.

Abstract

A general-purpose viscous flow code, DTNS3D, has been used to compute the strength and trajectories an isolated vortex and a vortex pair. Analytic solutions and previous computations are used to judge the accuracy of the th dimensional steady-state results. It is possible to track, quite accurately, the decay and translation of these vortex structure A byproduct of this study is some information on the limitations of the unsteady crossflow analogy and on the effect of ax velocity variations on vortex trajectories.
