Sphere wake
WebApr 5, 2004 · If in the subcritical regime the wake assumes a helical-like form due to the shedding of hairpin-like vortices at different azimuthal angles, in the supercritical regime the wake structure is characterized by “regular” shedding of hairpin-like vortices at approximately the same azimuthal angle and at a much higher frequency ( St ∼1.3) that is … WebSep 27, 2024 · When the spacing is twice larger than the sphere diameter, on the other hand, the flows in the gap and final wake tend to recover the axisymmetric feature, which is similar to that of a single sphere wake at the same Reynolds number.
