Edge flame

Last updated April 25, 2025

An edge flame or a triple flame refers to a stationary or moving flame edge in partially premixed reacting mixture. The canonical edge flame has a tribriachial structure that comprises two premixed flames, namely one fuel rich and one fuel lean, and a trailing diffusion flame. The theoretical development of triple flames was carried out by John W. Dold,^[1] Joel Daou and Amable Liñán.^[2]
