Propagation speeds and stretch rates measured along wrinkled flames to assess the theory of flame stretch

Combustion and Flame, 2003
Local propagation speeds and stretch rates were measured along a premixed flame that undergoes unsteady wrinkling in order to see if these two quantities correlate in the manner that is predicted by the theory of flame stretch. The Markstein number, which relates these two quantities, also was measured.

Stretching of polymer in a random flow: Effect of a shear rate

EPL (Europhysics Letters), 2010
The role of increasing shear rate on polymer extension and angular statistics in a random flow is studied. Large polymer extension results from a random part of a velocity field, whereas a shear component suppresses it although the coil-stretch transition occurs even at the highest shear rates.

Combustion in a stretched fuel strip with finite rate chemistry☆

Combustion and Flame, 1991
Abstract This article concerns a combined analytical and numerical study of finite rate exothermic chemical reactions in a one-dimensional fuel strip embedded in an oxidizing medium. The fuel and oxidizer undergo time dependent in-plane straining motion resembling a fuel strip that is being continuously stretched by the local velocity gradients in a ...

A rate-dependent analysis and experiment on the sheet-stretching process

Journal of Materials Processing Technology, 1993
Abstract A rate-dependent elasto-plastic finite-element formulation of boundary-value problems has been developed for the large deformation sheet-stretching process. The formulation used is based on the power form constitutive equation for the stress-strain-strain rate relation of the material.

On the mean stretch rate over a finite flame segment

2009
In this work, an approach is suggested to determine the mean flame stretch rate for a finite segment of a thin flame, in particular, for the entire flame. The suggested approach does not require averaging of local stretch rate at multiple flame locations. It is evidenced that available theoretical predictions of the mean stretch rate, which rely on the
