Convection in a sentence

Sometimes "convection" is even used to refer specifically to "free heat convection" (natural heat convection) as opposed to forced heat convection.

Gravitational or buoyant convection Gravitational convection is a type of natural convection induced by buoyancy variations resulting from material properties other than temperature.

Convection mechanisms Convection may happen in fluids at all scales larger than a few atoms.

Forced convection main In forced convection, also called heat advection, fluid movement results from external surface forces such as a fan or pump.

For example, convection may take place in a set of compositionally different layers, which may inhibit the upward heat transport ; perhaps double diffusive convection is a limiting factor.

For instance, a convection oven works by forced convection, as a fan which rapidly circulates hot air forces heat into food faster than would naturally happen due to simple heating without the fan.

Granules on the photosphere of the Sun are the visible tops of convection cells in the photosphere, caused by convection of plasma in the photosphere.

High values for the Earth's mantle indicates that convection within the Earth is vigorous and time-varying, and that convection is responsible for almost all the heat transported from the deep interior to the surface.

However, all types of buoyant convection, including natural convection, do not occur in microgravity environments.

Lately, the convection theory has been much debated as modern techniques based on 3D seismic tomography still fail to recognize these predicted large scale convection cells.

Medium-sized, low-mass stars like the Sun have a core region that is stable against convection, with a convection zone near the surface that mixes the outer layers.

Natural convection, or free convection, occurs due to temperature differences which affect the density, and thus relative buoyancy, of the fluid.

Natural convection will be more likely and/or more rapid with a greater variation in density between the two fluids, a larger acceleration due to gravity that drives the convection, and/or a larger distance through the convecting medium.

Other planets Jupiter 's atmosphere has multiple jet streams, caused by the convection cells that form the familiar banded color structure; on Jupiter, these convection cells are driven by internal heating.

The manifestation of this varying lateral density is mantle convection from buoyancy forces.sfn How mantle convection directly and indirectly relates to plate motion is a matter of ongoing study and discussion in geodynamics.

A multifunction air fryer is redundant if you already have a countertop full of other appliances, including a toaster, convection oven, and perhaps an indoor grill.

There is growing concern for an all-hazards threat, with soundings starting to pick up on the potential for a spin-up within pre-frontal convection, this mainly appears to be north and east of the Triangle.

Crucially, this added heat rises in a process called convection, similar to how boiling water propels rice around a pot.

Scattered moderate isolated to isolated strong convection is observed from 03°N to 10°N between 38°W and 48°W.

That’s a shame – Stephen Fry was really up for playing Dr Jonathan Convection.
