Summary

A flat premixed flame is stable when the burning velocity Su equals the gas velocity v0; it blows off when Su is smaller and flashes back when Su is larger. Based on Simmons (2002), p. 1-144 (Figure 1-9.1, redraw, do not copy).

Alt text: Three panels of a flat flame above a burner: stable when burning velocity equals gas velocity, blown off when slower, flashing back when faster.
