WebTo approximate the flux over the entire surface, we add the values of the flux on the small squares approximating small pieces of the surface (Figure 6.80). By Green’s theorem, the flux across each approximating square is a line integral over its boundary. WebIn any context where something can be considered flowing, such as a fluid, two-dimensional flux is a measure of the flow rate through a curve. The flux over the boundary of a region can be used to measure whether …

The word flux comes from Latin: fluxus means "flow", and fluere is "to flow". As fluxion, this term was introduced into differential calculus by Isaac Newton. The concept of heat flux was a key contribution of Joseph Fourier, in the analysis of heat transfer phenomena. His seminal treatise Théorie analytique de la … See more Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. Flux is a concept in applied mathematics and vector calculus which has many applications to See more In transport phenomena (heat transfer, mass transfer and fluid dynamics), flux is defined as the rate of flow of a property per unit area, which … See more • Mathematics portal • AB magnitude • Explosively pumped flux compression generator • Eddy covariance flux (aka, eddy correlation, eddy flux) • Fast Flux Test Facility See more • The dictionary definition of flux at Wiktionary See more General mathematical definition (surface integral) As a mathematical concept, flux is represented by the surface integral of a vector field See more • Browne, Michael, PhD (2010).

Web2 Answers Sorted by: 4 The flux through a surface is the amount of fluid that crosses the surface in a flow per unit time at any one instant. If the velocity field is v ( x), and the surface is S, it is the integral over the surface ∫ S v ⋅ n where n is the normal to the surface. shanghai novartis animal health co. ltd
