Navier–Stokes equation [Wikipedia] In physics, the Navier–Stokes equations, named after Claude-Louis Navier and George Gabriel Stokes, describe the motion of fluid substances. These equations arise from applying Newton's second law to fluid motion, together with the assumption that the stress in...

Taking the curl of the Navier-Stokes equation, the vorticity equation is given as ∂tΩ=∇×(v×Ω)+γ∇2Ω. with the vorticity Ω≡∇×v measuring the local circulation of the flow. From these two equations, one can derive balance equations of quadratic nonlinear invariants. The ...
The Navier-Stokes equation of two-dimensional neutral fluid turbulence is similar to three-dimensional case, except that \bm{ abla} should be replaced by \bm{ abla}_{\perp} with the anisotropy assum…
