Is heat flux a vector
WebFeb 2, 2011 · The heat flux vector is directed towards regions of lower temperature. Convective heat flux is proportional to the temperature difference between solid, liquid, or gaseous media participating in heat transfer. A heat transfer coefficient serves as the proportionality factor. WebDoes a heat flux vector at a point P on an isothermal surface of a medium have to be perpendicular to the surface at that point? yes, if the medium is stationary and has equal conductivity in all directions.
