Sentences with phrase «radiation flux density»

It is qdot = — DIV Fv where qdot is the monochromatic heat generation rate of matter per unit volume and Fv is the monochromatic radiation flux density.

Not exact matches

The calculations estimate the reduction in the energy flux density with distance away from the sun (Gauss» theorem) and the black body radiation describing the rate of planetary heat loss.

The atmosphere is analogous to a flexible lens that is shaped by the density distribution of the gas molecules, of the atmosphere in the space between the sphere holding them, and space; Incoming heat gets collected in many ways and places,, primarily by intermittent solar radiation gets stored, in vast quantities, and slowly but also a barrage of mass and energy fluxes from all directions; that are slowly transported great distances and to higher altitudes mostly by oceanic and atmospheric mass flows.

Certain things come out of it easily, such as the concept of black body radiation and balance of energy flux with energy density in a cavity (for example).
