Sentences with phrase «called vorticity»

It works not by spinning in the wind, but by taking advantage of a phenomenon called vorticity, or the Kármán vortex street, which is a «repeating pattern of swirling vortices.»

(In 2d, something called vorticity is conserved and flows don't go to shorter scales, because vortices can't kink.

In the so - called model numerics, a great deal of care is used in formulating the differential equation solution approach so as to explicitly conserve a number of quantities (mass, energy, water substance, angular momentum, linear momentum, vorticity) that are all important for the accurate representation of atmospheric dynamics.

If numerical methods can not accurately compute the solution of the basic dynamical system (so called dynamical cores) either because of ill posedness, fast exponential growth, or inadequate resolution to properly resolve the rapid nonlinear cascade of the vertical component of vorticity (requires unphysically large dissipation to overcome), then adding necessarily unphysical parameterizations to overcome these deficiencies can not lead to a correct physical solution as the resolution is reduced.
