भ्रमिलता(ξ):
यह संचलन का सीमित मान और एक बंद समोच्च क्षेत्र के अनुपात के रूप में परिभाषित किया गया है। यह एक द्रव पार्सल के स्थानीय घूर्णन को मापता है।
\({\bf{vorticity}} = \frac{{{\bf{Circulation}}}}{{{\bf{Area}}}}\)
भ्रमिलता को घूर्णी घटक के दुगने के रूप में परिभाषित किया गया है।
ω = 2ω,
लेकिन, \(\vec{\omega }=\frac{1}{2}\left( \nabla \times \vec{V} \right)\)
\(\Rightarrow \vec{\xi }=2~\vec{\omega }=2.\frac{1}{2}\left( \nabla \times \vec{V} \right)\)
\(\Rightarrow \vec{\xi }=\nabla \times \vec{V}\)
जहां \(\vec{V}\) वेग क्षेत्र का प्रतिनिधित्व करता है
\(\vec{V}=u\hat{i}+v\hat{j}+w\hat{k}\)
तो भ्रमिलता वेग कारक के कर्ल के बराबर है।
