Abstract
The paper reports an experimental and theoretical study of the interaction of two diffusion flames propagating over the surface of two different liquid fuels applied to both sides of a thin metal substrate. It is shown that in this system, there may be formation of a unified complex — a double‐sided flame which has the properties of a steady‐state flame with a peculiar structures. Some velocity and structural dependences for double‐sided flames are determined. A mathematical model for a double‐sided flame is proposed that adequately describes experimental relations. A physical model for a double‐sided flame with a pulsating flame of the heavier fuel is formulated.
