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/m ). It has both a direction and a magnitude, and so it is a vector quantity. To define the heat flux at a certain … Ver más For most solids in usual conditions, heat is transported mainly by conduction and the heat flux is adequately described by Fourier's law. Fourier's law in one dimension where Ver más The measurement of heat flux can be performed in a few different manners. A commonly known, but often impractical, method is performed … Ver más • Radiant flux • Latent heat flux • Rate of heat flow • Insolation • Heat flux sensor • Relativistic heat conduction Ver más One of the tools in a scientist's or engineer's toolbox is the energy balance.
