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.
