Abstract
The surface of samples of powder burning in a flow in the presence of erosion is spotted with roughnesses of almost-periodic structure [1]. Such roughnesses are also observed with the combustion of some ablating materials in a flow [2]. It has been observed that, with the unstable (resonance) combustion of powders, different acoustical modes correspond to the structure of the roughnesses [3]. One of the possible mechanisms of the formation of waves on the surface, developed in [4, 5], has still not received sufficient experimental confirmation. The present article discusses the laws governing the formation of a wave structure on the surface of various condensed substances, burning in a turbulent flow of the combustion products of ballistic powder N.
