Calculated as the curl of the fluid velocity, FTP, name this measure of the localized angular velocity per unit area of a fluid.
Longitudinal concavity gives rise to this phenomenon in the G?rtler Effect, which may be amplified by the introduction of Tollmien-Schlichting waves. The von Karman equation gives the net value for its measurement for isotropic cases of its occurrence, while another indicator of its presence is a Strouhal Number of at least 0.2. Its permeation of vector fields under Couette conditions is chaotic, though Kelvin's circulation theorem assigns it a constant in the case of incompressible inviscid fluids, and it must always equal zero in the application of Bernoulli's Law.
