(Color online) Instantaneous Mach number field and nondimensional pressure coefficient as a function of time, near the leading edge (black) and near the trailing edge (gray) at and (flow A).
Normalized eigenvalues (left axis—solid lines) and statistical content of the reduced-order basis (right axis—dashed lines) as a function of mode number in flows A and B .
(Color online) First four odd spatial POD modes associated to pressure in flow A (, ), where the von Kármán instability interacts with the buffet phenomenon. Positive (negative) values are denoted by solid (dashed) lines.
First four odd normalized POD dynamics (flow A): references issued from high-order database projections and prediction by 16-mode ROM (solid lines).
