Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy ). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed.
May 22, 2019 · Learn what convection currents are and how they are generated by density differences in fluids due to temperature gradients. See how convection currents occur in nature and engineering applications, such as atmospheric circulation and thermal columns.
Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow ).
