Summary
-
1.
Periodic variation of the thickness of the diffusion-temperature layer causes periodic oscillations of the flame height.
-
2.
The mechanism of sinusoidal or near-sinusoidal oscillation of the flame height can be explained, at least qualitatively, purely in terms of molecular radial diffusion of oxygen.
