Abstract

Synchronization of oscillations of thin elastic plates that are walls of a gas‐filled channel is considered. The gas motion is described by a system of Navier–Stokes equations, which is solved using the second‐order MacCormack method with time splitting. The motion of the channel walls is described by a system of geometrically nonlinear dynamic equations of the theory of this plates, which is solved by the finite‐difference method. Kinematic and dynamic contact conditions are imposed at the interface between the media. A numerical experiment is performed to determine typical dynamic regimes and study the transition of the aeroelastic system to in‐phase oscillations.
