Abstract

Asymptotic methods are used to investigate the regime of two interacting waveguides. As a result of an analysis of the dispersion relation short-wave instability of the acoustic type is detected. It is shown that this instability is convective. A qualitative comparison with direct numerical calculations is carried out using a simple model of the flow in the shock layer.
