Theoretical and experimental results of the trapezoid flags. (a) The critical velocity vs the dimensionless second moment of area for the trapezoid flags. The hollow circles and solid triangles correspond to the measured and , respectively. The solid line is the numerical result. The symbols above the dashed lines indicate the corresponding shapes of the model. (b) and (c) are snapshot sequences of the flutter flag for models (1) and (10), respectively. The left column is the experimental photos and the right is the numerical results.
