Conductive heat flux翻译
http://muchong.com/t-6144922-1 WebThermal heat flux is the rate of thermal energy flowing per unit area of the heat transfer surface per unit time. The heat flux density at a given point can be easily described with the help of Fourier’s law. When modeling the heat transfer in a fluid flow system, heat flux can be calculated for conduction, radiation, resistance, and diffusion.

WebConvective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water. In forced convection, air or water is forcibly moved across the body surface (such as in wind ... http://www2.ocean.washington.edu/oc540/lec02-3/
