Generalized beltrami flows and other closed-form solutions of an unsteady viscoelastic fluid

Abstract

We study flows of an unsteady non-Newtonian fluid by assuming the form of the vorticity a priori. The two forms that have been considered are ▽2ψ = F (t) ψ + G (t), which is known as the generalized Beltrami flow and ▽2ψ = f (t) ψ + g (t)y. Copyright © 2002 Hindawi Publishing Corporation.
