WebConvection involves the transfer of heat by the motion and mixing of "macroscopic" portions of a fluid (that is, the flow of a fluid past a solid boundary). The term natural convection is used if this motion and mixing is caused by density variations resulting from temperature differences within the fluid. The term forced convection is used if ... WebSep 9, 2024 · Heat flows in the opposite direction to the temperature gradient. The ratio of the rate of heat flow per unit area to the negative of the temperature gradient is called the thermal conductivity of the material: (4.3.1) d Q d t = − K A d T d x.
