Web2 de feb. de 2011 · Heat flux (W/m 2) is the rate of thermal energy flow per unit surface area of heat transfer surface, e.g., in a heat exchanger. Heat flux is the main parameter in calculating heat transfer. A generalized classification distinguishes between heat fluxes by convection, heat conduction, and radiation. Webq: heat flux (W/m 2 ); i.e., thermal power per unit area, ΔT: difference in temperature between the solid surface and surrounding fluid area (K) The heat transfer coefficient is the reciprocal of thermal insulance. This is used for building materials ( R-value) and for clothing insulation .
