Web31 jul. 2015 · In fluid mechanics, the helicity is defined as ∫R3u(x, t) ⋅ ω(x, t), where u(x, t) is a smooth solution of the Euler equations ∂tu + (u ⋅ ∇)u = − ∇p ∇ ⋅ u = 0, and ω is the vorticity ω = ∇ × u. We need to show that helicity is a conserved quantity. What I tried to do: We also have the Euler equations in vorticity form ...
