Asymmetries in Nominally Symmetric Flows

OJH Williams, AJ Smits - Annual Review of Fluid Mechanics, 2024 - annualreviews.org
Many flows that are expected to be symmetric are actually observed to be asymmetric. The
appearance of asymmetry in the face of no particular cause is a widespread although …
