In vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.
The meaning of DIVERGENCE is a drawing apart (as of lines extending from a common center).
The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point. This is the formula for divergence: div v → = ∇ ⋅ v → = ∂ v 1 ∂ x + ∂ v 2 ∂ y + ⋯. .
Sep 7, 2022 · Divergence measures the “outflowing-ness” of a vector field. If \(\vecs{v}\) is the velocity field of a fluid, then the divergence of \(\vecs{v}\) at a point is the outflow of the fluid less the inflow at the point.
a situation in which two things become different, or the difference between them increases: a divergence of opinion. The figures reveal a marked divergence between public sector pay settlements and those in the private sector.

5 days ago · The divergence of a vector field F, denoted div(F) or del ·F (the notation used in this work), is defined by a limit of the surface integral del ·F=lim_(V->0)(∮_SF·da)/V (1) where the surface integral gives the value of F integrated over a closed infinitesimal boundary surface S=partialV surrounding a volume element V, which is taken to ...
Divergence (div) is “flux density”—the amount of flux entering or leaving a point. Think of it as the rate of flux expansion (positive divergence) or flux contraction (negative divergence).
Topics. 7.1 Definition of Divergence. 7.2 Properties of Divergence. 7.3 What does the Divergence signify? Why is it important?
Divergence is a property exhibited by limits, sequences, and series. A series is divergent if the sequence of its partial sums does not tend toward some limit; in other words, the limit either does not exist, or is ±∞.
Dec 11, 2016 · The divergence of a vector field $ \mathbf{a} $ at a point $ x $ is denoted by $ (\operatorname{div} \mathbf{a})(x) $ or by the inner product $ \langle \nabla,\mathbf{a} \rangle (x) $ of the Hamilton operator $ \nabla \stackrel{\text{df}}{=} \left( \dfrac{\partial}{\partial x^{1}},\ldots,\dfrac{\partial}{\partial x^{n}} \right) $ and the vector ...
