Vorticity

${\displaystyle {\vec {\zeta }}=2{\vec {\omega }}{=}{{\vec {\nabla }}\times {\vec {V}}}}$

${\displaystyle \underbrace {{\frac {1}{2}}({\partial w \over \partial y}-{\partial v \over \partial z})} _{\omega _{x}}+\underbrace {{\frac {1}{2}}({\partial u \over \partial z}-{\partial w \over \partial x})} _{\omega _{y}}+\underbrace {{\frac {1}{2}}({\partial v \over \partial x}-{\partial u \over \partial y})} _{\omega _{z}}}$
