unusual facts about convection



Atmospheric circulation

Though cool and dry relative to equatorial air, air masses at the 60th parallel are still sufficiently warm and moist to undergo convection and drive a thermal loop.

Chandrasekhar number

The Chandrasekhar number is a dimensionless quantity used in magnetic convection to represent ratio of the Lorentz force to the viscosity.

Convection microwave

Companies such as Wolf, GE, Sharp, Samsung,Panasonic and Daewoo all currently produce convection microwaves.

Electro Thermal Dynamic Stripping Process

The difference between Electrical Resistance Heating (ERH) and ET-DSP is heat transfer due to convection.

History of climate change science

In 1967, taking advantage of the ability of digital computers to numerically integrate absorption curves, Syukuro Manabe and Richard Wetherald made the first detailed calculation of the greenhouse effect incorporating convection (the "Manabe-Wetherald one-dimensional radiative-convective model").

Thermomagnetic convection

B. A. Finlayson first explained in 1970 (in his paper "Convective instability of ferromagnetic fluids", Journal of Fluid Mechanics 40:753-767) how an external magnetic field imposed on a ferrofluid with varying magnetic susceptibility, e.g., due to a temperature gradient, results in a nonuniform magnetic body force, which leads to thermomagnetic convection.

Volcanism

Movement of molten rock in the mantle, caused by thermal convection currents, coupled with gravitational effects of changes on the earth's surface (erosion, deposition, even asteroid impact and patterns of post-glacial rebound) drive plate tectonic motion and ultimately volcanism.
