Cylinder aspect ratio
WebMar 15, 2024 · The aspect ratio (AR) defined by the characteristic length in the streamwise and transverse direction varies in the range 0.5 ≤ AR ≤ 2.0. The dynamic response is characterized as a function of reduced velocity. The streamlined profile of the elliptic cylinder results in a delay of the and a diminished strength of the averaged vorticity. WebOct 1, 2009 · Cylinders with four different aspect ratios ( L / D = 2, 5, 10, and 20), with angles of inclination 0 ⩽ α ⩽ 90 were considered. Each cylinder was placed in the domain shown in Fig. 1. The domain dimensions varied slightly between cases, but its rough dimensions are as given in Fig. 1.
