Implication

Experimental and theoretical study demonstrates cellular front formation in rich hydrocarbon flames, indicating that flame curvature directly governs front stability.

Key Points

To examine the mechanisms causing rich hydrocarbon flames to develop cellular structures and establish a theoretical framework for flame-front stability.
Observed laminar rich hydrocarbon flames inside tubes without approach-stream turbulence while varying fuel type, mixture composition, and pressure.
Formulated a first-order mathematical perturbation treatment of flame-front stability incorporating the dependence of burning velocity on flame-front curvature.
Rich hydrocarbon mixtures spontaneously developed cellular flame fronts in the complete absence of approach-stream turbulence.
First-order perturbation stability theory achieved qualitative agreement with experimental cell observations when accounting for burning velocity dependence on flame curvature.
