Title: Low-dimensional models of subcritical transition to turbulence
Authors: Baggett, Jeffrey S.
Trefethen, Lloyd N.
Keywords: theory center
Issue Date: Feb-1996
Publisher: Cornell University
Abstract: In the past five years, working largely independently, five groups of researchers have proposed low-dimensional models of the behavior of parallel shear flows at high Reynolds numbers. These models are compared, and it is found that they are more similar than their authors have recognized. Among other similarities, most of them exhibit a threshold amplitude c=O(R**alpha) as R to infinity for some alpha less than -1, where R is the Reynolds number, for perturbations of the laminar state that may excite transition to turbulence.
