Hydrogen ‘flame-bubbles’ are the small flames observed in very lean hydrogen/air mixtures. Previous estimates of the flame temperature fail to account for convection, and a simple mathematical model is proposed to remedy this. In addition, convectioe gradients generated by the buoyancy of the hot gases are proposed as a mechanism to overcome the instability that appears to be associated with the large curvature of the flames.
