Energyflux is the rate of transfer of energy through a surface. The quantity is defined in two different ways, depending on the context: Total rate of...
Poynting vector (or Umov–Poynting vector) represents the directional energyflux (the energy transfer per unit area, per unit time) or power flow of an electromagnetic...
heat flux or thermal flux, sometimes also referred to as heat flux density, heat-flow density or heat-flow rate intensity, is a flow of energy per unit...
radiometry, radiant flux or radiant power is the radiant energy emitted, reflected, transmitted, or received per unit time, and spectral flux or spectral power...
E_{\text{braking}}} the energyflux lost while braking and E recup {\displaystyle E_{\text{recup}}} the recuperated energyflux, an equilibrium is reached...
temperature. Energyflux is the rate of energy flow per unit area. Energyflux is expressed in units of W/m2, which is the number of joules of energy that pass...
0°) has a sound energyflux P = 0.3 mW. This is the parameter one would be interested in when converting noise back into usable energy, along with any...
is useful when a flux can be defined. To define flux, first there must be a quantity q which can flow or move, such as mass, energy, electric charge,...
radiation can be a small fraction of the energyflux. For example, the ratio of exergy flux to energyflux ( M / H ) {\displaystyle (M/H)} for graybody...
integrating radiant flux (or power) with respect to time. The symbol Qe is often used throughout literature to denote radiant energy ("e" for "energetic"...
vertical structures represent large stores of potential energy that can be converted to kinetic energy under the right circumstances.[citation needed] The...
for salt to melt the ice. There are several energyfluxes involved in the melting of snow. These fluxes can act in opposing directions, that is either...
are more than double humanity's current energy consumption from all primary sources, but most of this energyflux is not recoverable. In addition to the...
"heat flux" is used when what is meant is therefore more accurately called diffusive flux of internal energy; such usage of the term "heat flux" is a...
{S}}:\left(\nabla \mathbf {U} \right)=0,} with: (U + cg)E is the mean wave energy density flux, S is the radiation stress tensor and ∇U is the mean-velocity shear...
planetary equilibrium temperature. The solar flux absorbed by the planet from the star is equal to the flux emitted by the planet: F a b s = F e m i t {\displaystyle...
In spectroscopy, spectral flux density is the quantity that describes the rate at which energy is transferred by electromagnetic radiation through a real...
informal name for Energyflux. "Energy current" is a somewhat informal term that is used, on occasion, to describe the process of energy transfer in situations...
{rad}}=d^{2}E/dAdt} is defined as the energyflux over a surface, which can be expressed with the momentum flux using E = p c {\displaystyle E=pc} for...
In photometry, luminous flux or luminous power is the measure of the perceived power of light. It differs from radiant flux, the measure of the total...
