Energy flow

from Wikipedia, the free encyclopedia

Energy flow stands for:

In physics:

  • the flow of energy, see energy flow
    • generally the three components , and the energy-momentum tensor
    • specifically described in electrodynamics by the Poynting vector ( energy flux density in the electromagnetic field)
  • the (e.g. through a surface) flowing energy per period of time, also called energy flow strength , which has the same unit as the power (physics)

Figuratively:
