“…The LBM performance in solving the energy equation is compared against that of a FVM. The collapsed dimension method (CDM) is used to compute the radiative information [17,18] required as source in the energy equation, both in combination with the LBM and with the FVM. Results for the effects of the conduction-radiation parameter N, the scattering albedo x, the extinction coefficient b, and the aspect ratio Y/X where X and Y are the dimensions of the 2-D enclosure, are studied.…”

“…It is to be noted that using the block-off region procedure with the approach of the CDM discussed in [6] for the participating medium radiative heat transfer, Talukdar [7] has demonstrated the use of the CDM in calculating view factors in a 2-D rectangular geometry having a central blockage. In the present work, the formulation presented is a simple one.…”

“…Thus, in the CDM, the expression for radiative heat flux q because of radiation on/from one side of a surface (a hemisphere of actual intensities transformed to a semicircle of effective intensities) is given by [6].…”

“…In radiatively participating [6,7,9] as well as transparent medium [3][4][5], in calculating the heat flux at any point, in the approximate methods like the DOM [2], the DTM [4], the FVM [5], etc., spherical space (4π solid angle) is discretized into a finite number of elemental sub-solid angles. In each sub-solid angle, intensity is considered isotropic.…”

“…The collapsed dimension method (CDM) is an efficient method for solving radiative transport problems dealing with participating medium [6][7][8]. It has been extensively used for the radiative transport problems with participating medium.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
