Numerical Investigation of Unsteady Cavitation Flow around E779A Propeller in a Nonuniform Wake with an Insight on How Cavitation Influences Vortex by Chengzao Han, Yun Long, Xiaorui Bai, Bin Ji

“…The unsteady behavior of cavitation and side-entrant jet can both promote local vorticity generation and flow unsteadiness. In addition, it is indicated with the relative vorticity transport equation that the stretching term plays a major role in vorticity transportation, while baroclinic torque and Coriolis force term mainly influence the vorticity distribution along the liquid-vapor interface.…”

Identifying Ocean Submesoscale Activity From Vertical Density Profiles Using Machine Learning by Leyu Yao, John R. Taylor, Dani C. Jones, Scott D. Bachman

“…We show that the adapted PCM can identify regions with high submesoscale activity, as characterized by the vorticity field (i.e., where surface vertical vorticity ζ is similar to Coriolis frequency f and Rossby number Ro=ζ/f∼O(1)), using solely the vertical density profiles, without any additional information on the velocity, the profile location, or horizontal density gradients. …”

Generalized Beltrami flows and other closed-form solutions of an unsteady viscoelastic fluid by F. Labropulu

“…We study flows of an unsteady non-Newtonian fluid by assuming the form of the vorticity a priori. The two forms that have been considered are ∇2ψ=F(t)ψ+G(t), which is known as the generalized Beltrami flow and ∇2ψ=f(t)ψ+g(t)y.…”
