Heat flux

  • Heat Flux
  • 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 is the rate of heat energy transfer through a given surface per unit time. The SI derived unit of heat rate is joule per second, or watt. Heat flux density is the heat rate per unit area. In SI units, heat flux density is measured in [W/m2]. Heat rate is a scalar quantity, while heat flux is a vectorial 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 rate, as opposed to mass or momentum rate. 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。フーリエの法則によれば、熱流束は熱の流れる方向の温度勾配に比例する。その比例係数を熱伝導率(ρ:ロー)という。
