Divergence and curl in a vector field in terms of curvature and tortuosityLXIVLXIVLXIV
Mathematically, the curl of a vector field is the cross product of the gradient and a vector. How do you find the curl of a vector? To find the curl of a vector field, set up a 3x3 matrix where the unit vectors belong in row 1, the gradient belongs in row 2, and the vector ...

A vector field is usually the source of the circulation. If you had a paper boat in a whirlpool, the circulation would be the amount of force that pushed it along as it went in a circle. The more circulation, the more pushing force you have. ...

of a vector field A, the vector characteristic of a “rotating component” of field A. The curl is represented by the symbol rot A. It can be interpreted in the following manner: Let A be the velocity field of a fluid flow. At a given point of the flow we place a small wheel with...
Motivated by strong versions of Green's theorem, we give an example of a differentiable vector field for which the curl is continuous but not all the partial derivatives are continuous.doi:10.1080/00029890.2020.1815476Adam CoffmanYuan Zhang
