Vector Calculus: Finding out divergence and curl of vector field
We demonstrate that the azimuthal ambiguity that is present in solar vector magnetogram data can be resolved with line-of-sight and horizontal heliographic derivative information by using the divergence-free property of magnetic fields without additional assumptions. We discuss the specific derivative information that is sufficient to resolve the ambiguity away from disk center, with particular emphasis on the line-of-sight derivative of the various components of the magnetic field. Conversely, we also show cases where ambiguity resolution fails because sufficient line-of-sight derivative information is not available. For example, knowledge of only the line-of-sight derivative of the line-of-sight component of the field is not sufficient to resolve the ambiguity away from disk center. Creating analytically divergence-free velocity fields from grid-based data. We present a method, based on B-splines, to calculate a C2 continuous analytic vector potential from discrete 3D velocity data on a regular grid.
Kelvin s theorem is an outgrowth of the previously described properties of vorticity and circulation. Jan 22, kelvinstokes theorem the kelvinstokes theorem named lord kelvin and george stokes, also known as the curl theorem, is a theorem in vector calculus on r3. In fluid mechanics, kelvin s circulation theorem named after the irish scientist who published this theorem in 1 states in an inviscid, barotropic flow with conservative body forces, the circulation around a closed curve which encloses the same fluid elements moving with the fluid remains constant with time 2. Greens, stokes, and the divergence theorems khan academy. Thats stokess theorem actually the kelvin stokes theorem. Likewise, smooth solutions of navierstokes are characterized by a generalized kelvin s theorem, introduced by constantiniyer

Gibbon Professor J. D Gibbon1, Dept of jdgThese notes are not identical word-for-word with my lectures which will be given on a of these notes may contain more examples than the corresponding lecture while in othercases the lecture may contain more detailed working. I willNOTbe handing out copies ofthese notes you are therefore advised to attend lectures and take your The material in them is dependent upon the Vector algebra you were taught at A-leveland your 1st year. A summary of what you need to revise lies inHandout 1 : Thingsyou need to recall about Vector algebra which is also 1 of this Further handouts are : a Handout 2 : The role of grad, div and curl in Vector Calculus summarizes mostof the material in 3.

Once a coordinate system is fixed, a vector field is mathematically represented by a vector function of position coordinates : , , r F or z y x F O r F. Resolving the vector at each point into its three components, the vector field can be written as : k z y x F j z y x F i z y x F z y x F z y x. A smooth vector field implies that the three functions, , are smooth or differentiable functions of the three coordinates x,y,z.
The theorem is useful because it allows us to translate difficult line integrals into more simple double integrals, or difficult double integrals into more simple line integrals. The same idea is true of the Fundamental Theorem for Line Integrals:. Therefore, the circulation of a vector field along a simple closed curve can be transformed into a double integral and vice versa.
In this section, we state the divergence theorem, which is the final theorem of this type that we will study. The divergence theorem has many uses in physics; in particular, the divergence theorem is used in the field of partial differential equations to derive equations modeling heat flow and conservation of mass. We use the theorem to calculate flux integrals and apply it to electrostatic fields.
