Abstract: A slow laminar flame which is a thin (less than 1 mm) gas layer separating media of different densities is proposed as the inerface between gaseous media for laboratory studies of Richtmyer–Meshkov and Rayleigh–Taylor instabilities. The potential of the proposed approach to produce an interface is shown by the example of shock-wave interaction with a laminar flame in a lean (6 vol.%) hydrogen-air mixture. The development of Richtmyer–Meshkov instability at the interface between a heavy (cold) and a light (hot) mixtures was recorded by shadowgraphy.

Keywords: Richtmyer–Meshkov instability, laminar flame, shock wave.
