Abstract: A comparison of two approaches to describing a stretching spherical flame is made. Processing of a large amount of experimental data shows that the approach in which a parameter proportional to the strain rate is used as a small parameter gives a lower accuracy of approximation than the approach based on the use of the ratio of the flame thickness to the radius of curvature.

Keywords: spherical flames, flame stretching, flame speed, curvature effect.
