The Boussinesq (BOO-sihn-esk) approximation for this process allows differences in density to be ignored except when they affect buoyancy (BOY- uhn-see), and the Churchill-Bernstein equation can estimate the Nusselt numbers that describe this process. This process is associated with high Prandtl (PRAHND-tull) numbers, and Benard cells model this process in the Earth's mantle. This usually is caused by a combination of currents and diffusion, and the forced type can be caused by air conditioning and electric fans. Name this form of heat transfer that does not occur in solids which is often contrasted with radiation and conduction.
