Laminar convection with an absorbing and emitting gas

Abstract

The heat transfer and fluid flow are determined for fully deveIoped laminar flow in a vertical channel. The effects of natural and forced convection and thermal radiation are included in the analysis. The spectral variation of the radiation properties are included through the use of the total band absorp~ tance. The analysis is general and specific numerical results have been obtained for the 15 micron band of carbon dioxide. A simplified approach for large path is also presented which is in excellent agreement with the more exact results.

Models for Infrared Atmospheric Radiation

“…This correlation does not reduce to the correct limiting form in the square root limit [19]. Extensive use of this correlation has been made in various radiative transfer analyses in the past ten years (see, for example, [19,96,97,1041). The results of this correlation are compared with other correlations in A relatively simple continuous correlation for band absorptance, which was introduced first by Cess and Tiwari [19] and later applied by Cess and Ramanathan [110], is given by…”
