本文主要是在風洞中以煙線觀察 NACA 0015 機翼於不同的加速度上仰過程中,

Flow visualization of the vortical structures developed on a NACA 0015
airfoil pitching at constant acceleration has been studied in a wind tunnel. The
observations of the experiments may be benificial to the understanding of
initial acceleration effects on the development of the dynamic stall vortex that
occurs on a constant-rate pitching-up airfoil. It is found that for the case of
airfoil piching at a constant acceleration rate in the range studied there
exists a corresponding case of constant pitch rate, such that both the cases
have nearly identical flow structure at the same angle of attack. The effects of
acceleration and pitch rates on the dynamic stall vortex and shear layer
vortices are also discussed.
