The effect of small amplitude oscillatory forcing as a dynamic stabilization or destabilization mechanism for two-layer plane Couette-Poiseuille flow is studied using numerical and asymptotic methods. For example, the time-periodic oscillations may be due to the pump which generates the press-driven pipe flow.
