The divergence of the curl of any vector field is equal to zero: If φ is a scalar valued function and F is a vector field, then Generalizations [ edit]

WebThe divergence can also be deﬁned in two dimensions, but it is not fundamental. The divergence of F~ = hP,Qi is div(P,Q) = ∇ ·F~ = P x +Q y. In two dimensions, the divergence is just the curl of a −90 degrees rotated ﬁeld G~ = hQ,−Pi because div(G~) = Q x − P y = curl(F~). The divergence measures the ”expansion” of a ﬁeld. If a WebDec 20, 2024 · Roughly speaking, divergence measures the tendency of the fluid to collect or disperse at a point, and curl measures the tendency of the fluid to swirl around the point. Divergence is a scalar, that is, a single number, while curl is itself a vector. The magnitude of the curl measures how much the fluid is swirling, the direction indicates the ...
