Convection is caused by yeast releasing CO2. In fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling convection currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it ...

The convective Bénard cells are not unique and will usually appear only in the surface tension driven convection. In general the solutions to the Rayleigh and Pearson [ 15 ] analysis (linear theory) assuming an infinite horizontal layer gives rise to degeneracy meaning that many patterns may be obtained by the system.
The polar cell is a simple system with strong convection drivers. Though cool and dry relative to equatorial air, the air masses at the 60th parallel are still sufficiently warm and moist to undergo convection and drive a thermal loop. At the 60th parallel, the air rises to the tropopause (about 8 km at this latitude) and moves poleward.
Thermal image of a newly lit Ghillie kettle. The plume of hot air resulting from the convection current is visible. Convective flow may be transient (such as when a multiphase mixture of oil and water separates) or steady state (see convection cell). The convection may be due to gravitational, electromagnetic or fictitious body forces.
The delicate charm of a butterfly, with its fabulous fluttering wings and jewel-toned hues, is a sight to behold.Even so, you may have, at some point in your life, wondered if these colorful ...
Earth's lithosphere includes upwards heat flow, partial convection, and a metal-layer core. Stratification is commonly seen in the planetary sciences. Solar energy passes as visible radiation through the air, and is absorbed by the ground, to be re-emitted as heat radiation.
Here we explain the meaning behind butterfly colors. Different cultures believe that the color of a butterfly can symbolize everything from creativity to evil. Here we explain the meaning behind ...
