Heat flux

  • Heat Flux
definition
  • The measurement of the heat flux or heat loss from open ocean areas within the sea ice pack is important for the study of energy balance in the polar regions and local and regional climatology. Heat loss through the open water is 100 times more than through thick ice.

Abstract from DBPedia
    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 area per unit time. In SI its units are watts per square metre (W/m2). It has both a direction and a magnitude, and so it is a vector quantity. To define the heat flux at a certain point in space, one takes the limiting case where the size of the surface becomes infinitesimally small. Heat flux is often denoted , the subscript q specifying heat flux, as opposed to mass or momentum flux. Fourier's law is an important application of these concepts.

    熱流束（ねつりゅうそく、英: heat flux）とは、流束のひとつで、単位時間に単位面積を横切る熱量である。 単位には W/m2 が用いられる。
