energy flux
Energy flux is the rate of transfer of energy through a surface. The quantity is defined in two different ways, depending on the context:
# Rate of energy transfer per unit area.〔(【引用サイトリンク】title=Energy flux )〕 (SI units: W·m−2 = J·m−2·s−1)
#
* This is a vector quantity, its components being determined in terms of the normal (perpendicular) direction to the surface of measurement.
#
* This is sometimes called ''energy flux density'', to distinguish it from the second definition.
#
* Radiative flux, heat flux, and sound energy flux are specific cases of energy flux density.
# Total rate of energy transfer.〔(【引用サイトリンク】title=Solar Physics Glossary )〕 (SI units: W = J·s−1)
#
* This is sometimes informally called ''energy current''.
