Abstract: Within the framework of the triple-deck theory, it is shown that the growth of the relative wall velocity in the Poiseuille–Couette flow leads to perturbations splitting into two wave packets, of which one grows faster and propagates at a higher velocity.

Key words: Poiseuille–Couette flow, Tollmien–Schlichting wave, wave packets, asymptotic expansions, triple-deck theory.
