Simulation parameters are comparable to the 3D geometry, (see Fig. 2): (d/B) = 2.24, A3 = 6 in, σ=3.65 rad/s. The hydrodynamic coefficients μ33 and λT for each shape are shown in the upper left corner of each plot. Note: B is the two-dimensional beam, which is the same value as the three-dimensional diameter, D.
