A loop of moving fluid (such as air or water) in which the motion results from differences in density caused by differences in temperature.

plural of convection cell

The transfer of heat by the movement of a fluid, usually as the result of convection

The convection (carriage) of contents of a fluid, such as mass or (especially) heat, by means of currents induced in the fluid by a force which is not dependent on density changes in the fluid induced by heat.

(physics) The convection (carriage) of contents of a fluid, such as mass or (especially) heat, by means of currents induced in the fluid by a buoyancy force which is dependent on an acceleration (such as gravity) acting upon density changes in the fluid which are induced by heat.

free convection

(physics) The convection (carriage) of contents of a fluid, such as mass or heat, by means of currents induced in the fluid by buoyancy forces which are dependent on gravity acting upon density differences within the fluid.

plural of convection oven

an oven that features fans to recirculate heated air to accelerate heating provided by traditional radiant heat sources found in the oven

convection microwave oven
