WebFeb 11, 2016 · Momentum conservation is the equation ∂ ∂ t π i + ∇ j τ i j = 0 where π i = ρ v i is the momentum density. Using τ i j = P δ i j + ρ v i v j this equation is equivalent to the Euler equation, and including dissipative stresses gives the Navier-Stokes equation. WebThe Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is By setting the Cauchy stress tensor to be the sum of a viscosity term (the deviatoric stress) and a pressure term (volumetric stress), we arrive at Cauchy momentum equation (convective form) where WebStokes theorem says that ∫F·dr = ∬curl (F)·n ds. If you think about fluid in 3D space, it could be swirling in any direction, the curl (F) is a vector that points in the direction of the AXIS OF ROTATION of the swirling fluid. curl (F)·n picks out the curl who's axis of rotation is normal/perpendicular to the surface. five handicap
