Abstract

To determine the unstretched adiabatic flame speed most experiments measure the stretched adiabatic flame speed and extrapolate the measured speeds to zero stretch. Currently linear extrapolation is prevalent; however, the phenomenon is inherently nonlinear. A nonlinear method of extrapolation is proposed which allows a more accurate extrapolation. Experimental data from both counterflow and outwardly propagating spherical flames were analyzed using nonlinear extrapolation and compare favorably with one another. It is found that linear extrapolation tends to overestimate the unstretched flame speed.
