WebCurl is an operator which takes in a function representing a three-dimensional vector field and gives another function representing a different three-dimensional vector field. If a fluid flows in three-dimensional … WebMay 28, 2016 · The curl of a vector field measures infinitesimal rotation. Rotations happen in a plane! The plane has a normal vector, and that's where we get the resulting vector field. So we have the following operation: vector field → planes of rotation → normal vector field This two-step procedure relies critically on having three dimensions.
