Cylinder aspect ratio
In projective geometry, a cylinder is simply a cone whose apex (vertex) lies on the plane at infinity. If the cone is a quadratic cone, the plane at infinity (which passes through the vertex) can intersect the cone at two real lines, a single real line (actually a coincident pair of lines), or only at the vertex. These cases give rise to the hyperbolic, parabolic or elliptic cylinders respectively. This concept is useful when considering degenerate conics, which may include the cylindrical co… 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.

Aspect ratio was found to be a significant factor in the difference between shedding frequencies of the two cylinders ...
The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do not represent actual widths and heights but, rather, the proportion between width and height.
