摘要：

A turbulent flow past two symmetric airfoils, whose bow and aft portions are circular arcs, whereas midparts are flat, is studies numerically. The amplitude of lift coefficient oscillations versus the free-stream Mach number M∞ is analyzed at zero angle of attack. Ranges of M∞ in which there exist flow bifurcations are determined.
