Vortex shedding phenomenon simulated in CFD: (a) (b) pressure coefficients at two instants; (c) (d) corresponding velocity contour. The shedding frequency is about 0.17 Hz, which corresponds to a Strouhal number of about 0.2. The rectangular section resulted in a relatively high response in the -direction under smooth flow ( ).
