natural convection

natural convection

[′nach·rəl kən′vek·shən] (thermodynamics) Convection in which fluid motion results entirely from the presence of a hot body in the fluid, causing temperature and hence density gradients to develop, so that the fluid moves under the influence of gravity. Also known as free convection.

natural convection

The convection resulting from the flow of air caused by temperature differences in an enclosed space, as opposed to the flow of air caused by a fan. Also known as free convection.
