Sentences with phrase «radiative heat transfer between»

I am not saying that: What I am saying is that the spontaneous process of radiative heat transfer between two objects consists of two sub-processes: radiation from the hot object passing to the cold object and radiation from the cold object passing to the hot object.

From this layman's perspective you are discussing NET radiative heat transfer between non-gaseous objects thus infering wide band land wave radiation is emitted / absorbed by the surface of each object.

In any introductory engineering heat transfer text, you will see that the net radiative heat transfer between two objects (1 and 2) is given as:

But predicting such radiative heat transfer between extremely close objects has proven elusive for the past 50 years.

Not exact matches

The discussion about radiative heat transfer shows how temperature differences regulate the amount of energy transferred between objects.

The core science, the radiative transfer equations that determine the way increasing CO2 increases the temperatures gradient between the emission altitude and the surface, derived from military research on heat seeking missile and detection systems.

The big difference between this scenario is that the radiation from the lamp AND the radiation from the glass originate in materials at significantly higher temperatures than the gases and hence heat IS transferring from HOT to COLD unlike the fanciful «back radiative greenhouse effect» which truly defies the laws of Physics relying instead on pixie dust magic!

It is essentially the result of a balance between (a) the stabilizing effect of upward heat transport in moist and dry convection on both small and large scales and (b), the destabilizing effect of radiative transfer.

«in an isotropic non GHG world, the net would be zero, as the mean conduction flux would equalize, but in our earth it is still nearly zero» if the atmosphere were isothermal at the same temperature as the surface then exactly the downwelling radiation absorbed by the surface would be equal to the radiation of th surface absorbed by the air (or rather by its trace gases) and both numbers would be (1 - 2E3 (t (nu)-RRB--RRB- pi B (nu, T) where t (nu) is the optical thickness, B the Planck function, nu the optical frequency and T the temperature; as the flow from the air absorbed by the surface is equal to the flow from the surface absorbed by the air, the radiative heat transfer is zero between surface and air.

Unfortunately radiative heat transfer plays a relatively small role in the heat transfer processes occurring between a sphere and a relatively dense, gaseous atmosphere under the influence of a gravitational field.

Backradiation is a silly term used to explain half of the radiative heat transfer system between the Earth's surface and the atmosphere.
